Added support for 1000BASE-BX, i.e. Gigabit Ethernet over single strand
of single-mode fiber.
The initialization of a 1000BASE-BX SFP is the same as 1000BASE-SX/LX
with the only difference that the Bit Rate Nominal Value must be
checked to make sure it is a Gigabit Ethernet transceiver, as described
by the SFF-8472 specification.
This was tested with the FS.com SFP-GE-BX 1310/1490nm 10km transceiver:

Linux users sometimes need an easy way to check current values of module
parameters. For example the module may be manually reloaded with different
parameters. Make these visible and readable in the /sys filesystem to allow
that. But don't make the "debug" module parameter visible as debugging is
enabled via ethtool msglvl.

The indentation for ice_set_ctx and ice_write_rxq_ctx breaks the function
name after the return type. This style of breaking is used a lot throughout
the ice driver, even in cases where its not actually helpful for
readability. We no longer prefer this style of line splitting in the
driver, and new code is avoiding it.
Normally, I would leave this alone unless the actual function contents or
description needed updating. However, a future change is going to add
inverse functions for converting packed context to unpacked context
structures. To keep this code uniform with the existing set functions, fix
up the style to the modern format of keeping the type on the same line.

The functions used to pack the Tx and Rx context into the hardware format
rely on using BIT() and then subtracting 1 to get a bitmask. These
functions even have a comment about how x86 machines can't use this method
for certain widths because the SHL instructions will not work properly.
The Linux kernel already provides the GENMASK macro for generating a
suitable bitmask. Further, GENMASK is capable of generating the mask
including the shift_width. Since width is the total field width, take care
to subtract one to get the final bit position.
Since we now include the shifted bits as part of the mask, shift the source
value first before applying the mask.

In ice_common.c there are 4 functions used for converting the unpacked
software Tx and Rx context structure data into the packed format used by
hardware. These functions have extremely generic names:
* ice_write_byte
* ice_write_word
* ice_write_dword
* ice_write_qword
When I saw these function names my first thought was "write what? to
where?". Understanding what these functions do requires looking at the
implementation details. The functions take bits from an unpacked structure
and copy them into the packed layout used by hardware.
As part of live migration, we will want functions which perform the inverse
operation of reading bits from the packed layout and copying them into the
unpacked format. Naming these as "ice_read_byte", etc would be very
confusing since they appear to write data.
In preparation for adding this new inverse operation, rename the existing
functions to use the prefix "ice_pack_ctx_". This makes it clear that they
perform the bit packing while copying from the unpacked software context
structure to the packed hardware context.
The inverse operations can then neatly be named ice_unpack_ctx_*, clearly
indicating they perform the bit unpacking while copying from the packed
hardware context to the unpacked software context structure.

When initializing over virtchnl, the PF is required to pass a VSI ID to the
VF as part of its capabilities exchange. The VF driver reports this value
back to the PF in a variety of commands. The PF driver validates that this
value matches the value it sent to the VF.
Some hardware families such as the E700 series could use this value when
reading RSS registers or communicating directly with firmware over the
Admin Queue.
However, E800 series hardware does not support any of these interfaces and
the VF's only use for this value is to report it back to the PF. Thus,
there is no requirement that this value be an actual VSI ID value of any
kind.
The PF driver already does not trust that the VF sends it a real VSI ID.
The VSI structure is always looked up from the VF structure. The PF does
validate that the VSI ID provided matches a VSI associated with the VF, but
otherwise does not use the VSI ID for any purpose.
Instead of reporting the VSI number relative to the PF space, report a
fixed value of 1. When communicating with the VF over virtchnl, validate
that the VSI number is returned appropriately.
This avoids leaking information about the firmware of the PF state.
Currently the ice driver only supplies a VF with a single VSI. However, it
appears that virtchnl has some support for allowing multiple VSIs. I did
not attempt to implement this. However, space is left open to allow further
relative indexes if additional VSIs are provided in future feature
development. For this reason, keep the ice_vc_isvalid_vsi_id function in
place to allow extending it for multiple VSIs in the future.
This change will also simplify handling of live migration in a future
series. Since we no longer will provide a real VSI number to the VF, there
will be no need to keep track of this number when migrating to a new host.

The ice_vc_fdir_param_check() function validates that the VSI ID of the
virtchnl flow director command matches the VSI number of the VF. This is
already checked by the call to ice_vc_isvalid_vsi_id() immediately
following this.
This check is unnecessary since ice_vc_isvalid_vsi_id() already confirms
this by checking that the VSI ID can locate the VSI associated with the VF
structure.
Furthermore, a following change is going to refactor the ice driver to
report VSI IDs using a relative index for each VF instead of reporting the
PF VSI number. This additional check would break that logic since it
enforces that the VSI ID matches the VSI number.
Since this check duplicates the logic in ice_vc_isvalid_vsi_id() and gets
in the way of refactoring that logic, remove it.

The ice_vc_isvalid_q_id() function takes a VSI index and a queue ID. It
looks up the VSI from its index, and then validates that the queue number
is valid for that VSI.
The VSI ID passed is typically a VSI index from the VF. This VSI number is
validated by the PF to ensure that it matches the VSI associated with the
VF already.
In every flow where ice_vc_isvalid_q_id() is called, the PF driver already
has a pointer to the VSI associated with the VF. This pointer is obtained
using ice_get_vf_vsi(), rather than looking up the VSI using the index sent
by the VF.
Since we already know which VSI to operate on, we can modify
ice_vc_isvalid_q_id() to take a VSI pointer instead of a VSI index. Pass
the VSI we found from ice_get_vf_vsi() instead of re-doing the lookup. This
removes some unnecessary computation and scanning of the VSI list.
It also removes the last place where the driver directly used the VSI
number from the VF. This will pave the way for refactoring to communicate
relative VSI numbers to the VF instead of absolute numbers from the PF
space.

This error message is at best not really helpful and at worst
misleading. If we're here in idpf_intr_rel we're likely trying to do
remove or reset. If we're in reset, this message will fail because we
lose the virtchnl on reset and HW is going to clean up those resources
regardless in that case. If we're in remove and we get an error here,
we're going to reset the device at the end of remove anyway so not a big
deal. Just remove this message it's not useful.

While we're here improving virtchnl we can include two minor fixes for
the lower level ctrlq flow.
This adds a memory barrier to idpf_post_rx_buffs before we update tail
on the controlq. We should make sure our writes have had a chance to
finish before we tell HW it can touch them.
This also removes some defensive programming in idpf_ctrlq_recv. The
caller should not be using a num_q_msg value of zero or more than the
ring size and it's their responsibility to call functions sanely.

In idpf_remove we need to tear down the virtchnl core with
idpf_vc_core_deinit so we can free up resources and leave things in a
good state. However, in the case where we failed to establish VC
communications we may not have ever actually successfully initialized
the virtchnl core.
This fixes it by setting a bit once we successfully init the virtchnl
core. Then, in deinit, we'll check for it before going on further,
otherwise we just return. Also clear the bit at the end of deinit so we
know it's gone now.

There are situations where the driver needs to add a MAC filter but
we're explicitly not allowed to sleep so we can wait for a virtchnl
message to complete.
This adds an async_handler for asynchronously sent messages for MAC
filters so that we can better handle if there's an error of some kind.
If success we don't need to do anything else, but if we failed to
program the new filter we really should remove it from our list of MAC
filters. If we don't remove bad filters, what I expect to happen is
after a reset of some kind we try to program the MAC filter again and it
fails again. This is clearly wrong and I would expect to be confusing
for the user.
It could also be the failure is for a delete MAC filter message but
those filters get deleted regardless. Not much we can do about a delete
failure.

This takes care of RSS/SRIOV/MAC and other misc virtchnl messages. This
again is mostly mechanical.
In absence of an async_handler for MAC filters, this will simply
generically report any errors from idpf_vc_xn_forward_async. This
maintains the existing behavior. Follow up patch will add an async
handler for MAC filters to remove bad filters from our list.
While we're here we can also make the code much nicer by converting some
variables to auto-variables where appropriate. This makes it cleaner and
less prone to memory leaking.
There's still a bit more cleanup we can do here to remove stuff that's
not being used anymore now; follow-up patches will take care of loose
ends.

This reworks queue specific virtchnl messages to use the added
transaction API. It is fairly mechanical and generally makes the
functions using it more simple. Functions using transaction API no
longer need to take the vc_buf_lock since it's not using it anymore.
After filling out an idpf_vc_xn_params struct, idpf_vc_xn_exec takes
care of the send and recv handling.
This also converts those functions where appropriate to use
auto-variables instead of manually calling kfree. This greatly
simplifies the memory alloc paths and makes them less prone memory
leaks.

This starts refactoring how virtchnl messages are handled by adding a
transaction manager (idpf_vc_xn_manager).
There are two primary motivations here which are to enable handling of
multiple messages at once and to make it more robust in general. As it
is right now, the driver may only have one pending message at a time and
there's no guarantee that the response we receive was actually intended
for the message we sent prior.
This works by utilizing a "cookie" field of the message descriptor. It
is arbitrary what data we put in the cookie and the response is required
to have the same cookie the original message was sent with. Then using a
"transaction" abstraction that uses the completion API to pair responses
to the message it belongs to.
The cookie works such that the first half is the index to the
transaction in our array, and the second half is a "salt" that gets
incremented every message. This enables quick lookups into the array and
also ensuring we have the correct message. The salt is necessary because
after, for example, a message times out and we deem the response was
lost for some reason, we could theoretically reuse the same index but
using a different salt ensures that when we do actually get a response
it's not the old message that timed out previously finally coming in.
Since the number of transactions allocated is U8_MAX and the salt is 8
bits, we can never have a conflict because we can't roll over the salt
without using more transactions than we have available.
This starts by only converting the VIRTCHNL2_OP_VERSION message to use
this new transaction API. Follow up patches will convert all virtchnl
messages to use the API.

ice_qp_dis() currently does things in very mixed way. Tx is stopped
before disabling IRQ on related queue vector, then it takes care of
disabling Rx and finally NAPI is disabled.
Let us start with disabling IRQs in the first place followed by turning
off NAPI. Then it is safe to handle queues.
One subtle change on top of that is that even though ice_qp_ena() looks
more sane, clear ICE_CFG_BUSY as the last thing there.

Currently routines that are supposed to toggle state of ring pair do not
take care of associated interrupt with queue vector that these rings
belong to. This causes funky issues such as dead interface due to irq
misconfiguration, as per Pavel's report from Closes: tag.
Add a function responsible for disabling single IRQ in EIMC register and
call this as a very first thing when disabling ring pair during xsk_pool
setup. For enable let's reuse ixgbe_irq_enable_queues(). Besides this,
disable/enable NAPI as first/last thing when dealing with closing or
opening ring pair that xsk_pool is being configured on.

The i211 requires the same PTP timestamp adjustments as the i210,
according to its datasheet. To ensure consistent timestamping across
different platforms, this change extends the existing adjustments to
include the i211.
The adjustment result are tested and comparable for i210 and i211 based
systems.

Commit 91fdbce7e8d6 ("ice: Add support in the driver for associating
queue with napi") invoked the netif_queue_set_napi() call. This
kernel function requires to be called with rtnl_lock taken,
otherwise ASSERT_RTNL() warning will be triggered. ice_vsi_rebuild()
initiating this call is under rtnl_lock when the rebuild is in
response to configuration changes from external interfaces (such as
tc, ethtool etc. which holds the lock). But, the VSI rebuild
generated from service tasks and resets (PFR/CORER/GLOBR) is not
under rtnl lock protection. Handle these cases as well to hold lock
before the kernel call (by setting the 'locked' boolean to false).
netif_queue_set_napi() is also used to clear previously set napi
in the q_vector unroll flow. Handle this for locked/lockless execution
paths.

Do not allow to acquire data or alter configuration of dpll and pins
through firmware if PF reset is in progress, this would cause confusing
netlink extack errors as the firmware cannot respond or process the
request properly during the reset time.
Return (-EBUSY) and extack error for the user who tries access/modify
the config of dpll/pin through firmware during the reset time.
The PF reset and kernel access to dpll data are both asynchronous. It is
not possible to guard all the possible reset paths with any determinictic
approach. I.e., it is possible that reset starts after reset check is
performed (or if the reset would be checked after mutex is locked), but at
the same time it is not possible to wait for dpll mutex unlock in the
reset flow.
This is best effort solution to at least give a clue to the user
what is happening in most of the cases, knowing that there are possible
race conditions where the user could see a different error received
from firmware due to reset unexpectedly starting.
Test by looping execution of below steps until netlink error appears:
- perform PF reset
$ echo 1 > /sys/class/net/<ice PF>/device/reset

The value of phase_adjust for input pin shall be updated in

firmware query function call - a pin's struct field pointer where the
phase_adjust value during driver runtime is stored.
Previously the phase_adjust used to misinform user about actual
phase_adjust value. I.e., if phase_adjust was set to a non zero value and
if driver was reloaded, the user would see the value equal 0, which is
not correct - the actual value is equal to value set before driver reload.

Fix the connection state between source DPLL and output pin, updating the
attribute 'state' of 'parent_device'. Previously, the connection state
was broken, and didn't reflect the correct state.
When 'state_on_dpll_set' is called with the value
'DPLL_PIN_STATE_CONNECTED' (1), the output pin will switch to the given
DPLL, and the state of the given DPLL will be set to connected.
E.g.:
--do pin-set --json '{"id":2, "parent-device":{"parent-id":1,
"state": 1 }}'
This command will connect DPLL device with id 1 to output pin with id 2.
When 'state_on_dpll_set' is called with the value
'DPLL_PIN_STATE_DISCONNECTED' (2) and the given DPLL is currently
connected, then the output pin will be disabled.
E.g:
--do pin-set --json '{"id":2, "parent-device":{"parent-id":1,
"state": 2 }}'
This command will disable output pin with id 2 if DPLL device with ID 1 is
connected to it; otherwise, the command is ignored.

The VEB (virtual embedded switch) as a switch element can be
connected according datasheet though its uplink to:
- Physical port
- Port Virtualizer (not used directly by i40e driver but can
be present in MFP mode where the physical port is shared
between PFs)
- No uplink (aka floating VEB)
But VEB uplink cannot be connected to another VEB and any attempt
to do so results in:
"i40e 0000:02:00.0: couldn't add VEB, err -EIO aq_err I40E_AQ_RC_ENOENT"
that indicates "the uplink SEID does not point to valid element".
Remove this logic from the driver code this way:
1) For debugfs only allow to build floating VEB (uplink_seid == 0)
or main VEB (uplink_seid == mac_seid)
2) Do not recurse in i40e_veb_link_event() as no VEB cannot have
sub-VEBs
3) Ditto for i40e_veb_rebuild() + simplify the function as we know
that the VEB for rebuild can be only the main LAN VEB or some
of the floating VEBs
4) In i40e_rebuild() there is no need to check veb->uplink_seid
as the possible ones are 0 and MAC SEID
5) In i40e_vsi_release() do not take into account VEBs whose
uplink is another VEB as this is not possible
6) Remove veb_idx field from i40e_veb as a VEB cannot have
sub-VEBs

Although the i40e supports so-called floating VEB (VEB without
an uplink connection to external network), this support is
broken. This functionality is currently unused (except debugfs)
but it will be used by subsequent series for switchdev mode
slow-path. Fix this by following:
1) Handle correctly floating VEB (VEB with uplink_seid == 0)
in i40e_reconstitute_veb() and look for owner VSI and
create it only for non-floating VEBs and also set bridge
mode only for such VEBs as the floating ones are using
always VEB mode.
2) Handle correctly floating VEB in i40e_veb_release() and
disallow its release when there are some VSIs. This is
different from regular VEB that have owner VSI that is
connected to VEB's uplink after VEB deletion by FW.
3) Fix i40e_add_veb() to handle 'vsi' that is NULL for floating
VEBs. For floating VEB use 0 for downlink SEID and 'true'
for 'default_port' parameters as per datasheet.
4) Fix 'add relay' command in i40e_dbg_command_write() to allow
to create floating VEB by 'add relay 0 0' or 'add relay'

Add two helpers i40e_(veb|vsi)_get_by_seid() to find corresponding
VEB or VSI by their SEID value and use these helpers to replace
existing open-coded loops.

Introduce i40e_for_each_vsi() and i40e_for_each_veb() helper
macros and use them to iterate relevant arrays.
Replace pattern:
for (i = 0; i < pf->num_alloc_vsi; i++)
by:
i40e_for_each_vsi(pf, i, vsi)
and pattern:
for (i = 0; i < I40E_MAX_VEB; i++)
by
i40e_for_each_veb(pf, i, veb)
These macros also check if array item pf->vsi[i] or pf->veb[i]
are not NULL and skip such items so we can remove redundant
checks from loop bodies.

Add support for LEDs on i225/i226. The LEDs can be controlled via sysfs
from user space using the netdev trigger. The LEDs are named as
igc-<bus><device>-<led> to be easily identified.
Offloading link speed and activity are supported. Other modes are simulated
in software by using on/off. Tested on Intel i225.
