When link is owned by manageability, the driver is not allowed to fiddle
with link. FW returns ICE_AQ_RC_EMODE if the driver attempts to do so.
This patch adds a new function ice_set_link which abstracts the call to
ice_aq_set_link_restart_an and provides a clean way to turn on/off link.
While making this change, I also spotted that an int variable was being
used to hold both an ice_status return code and the Linux errno return
code. This pattern more often than not results in the driver inadvertently
returning ice_status back to kernel which is a major boo-boo. Clean it up.

Remove the recursive way of adding the nodes to the layer in order
to reduce the stack usage. Instead the algorithm is modified to use
a while loop.
The previous code was scanning recursively the nodes horizontally.
The total stack consumption will be based on number of nodes present
on that layer. In some cases it can consume more stack.

ice_aqc_opc_lldp_stop
ice_aqc_opc_lldp_start
ice_aqc_opc_lldp_filter_ctrl
This change follows the latest guidelines from HW team. It is
better to retry the same AQ command several times, as the result

struct ice_vsi has two fields, state and flags which seem to
be serving the same purpose. Consolidate them into one field
'state'.
enum ice_state is used to represent state information of the PF.
While some of these enum values can be use to represent VSI state,
it makes more sense to represent VSI state with its own enum. So
derive a new enum ice_vsi_state from ice_vsi_flags and ice_state
and use it. Also rename enum ice_state to ice_pf_state for clarity.

Currently ice_set/get_rss are used to set/get the RSS LUT and/or RSS
key. However nearly everywhere these functions are called only the LUT
or key are set/get. Also, making this change reduces how many things
ice_set/get_rss are doing. Fix this by adding ice_set/get_rss_lut and
ice_set/get_rss_key functions.
Also, consolidate all calls for setting/getting the RSS LUT and RSS Key

Update ice_aq_get_rss_lut() and ice_aq_set_rss_lut() to take a new
structure ice_aq_get_set_rss_params instead of passing individual
parameters. This is done for 2 reasons:
1. Reduce the number of parameters passed to the functions.
2. Reduce the amount of change required if the arguments ever need to be
updated in the future.
Also, reduce duplicate code that was checking for an invalid vsi_handle
and lut parameter by moving the checks to the lower level
__ice_aq_get_set_rss_lut().

Currently, ice_vsi_setup_q_map() depends on the VSI's rss_size. However,
the Rx Queue Mapping section of the VSI context has no dependency on RSS.
Instead, limit the maximum number of Rx queues per TC based on the Rx
Queue mapping section of the VSI context, which currently allows for up
to 256 Rx queues per TC.

There is an issue when the Tx or Rx ring size increases using
'ethtool -L ...' where the new rings don't get the correct ITR
values because when we rebuild the VSI we don't know that some
of the rings may be new.
Fix this by looking at the original number of rings and
determining if the rings in ice_vsi_rebuild_set_coalesce()
were not present in the original rings received in
ice_vsi_rebuild_get_coalesce().
Also change the code to return an error if we can't allocate
memory for the coalesce data in ice_vsi_rebuild().

Once a netdev is registered, the corresponding network interface can
be immediately used by userspace utilities (like say NetworkManager).
This can be problematic if the driver technically isn't fully up yet.
Move netdev registration to the end of probe, as by this time the
driver data structures and device will be initialized as expected.
However, delaying netdev registration causes a failure in the aRFS flow
where netdev->reg_state == NETREG_REGISTERED condition is checked. It's
not clear why this check was added to begin with, so remove it.
Local testing didn't indicate any issues with this change.
The state bit check in ice_open was put in as a stop-gap measure to
prevent a premature interface up operation. This is no longer needed,
so remove it.

The original purpose of the ICE_DCBNL_DEVRESET was to protect
the driver during DCBNL device resets. But, the flow for
DCBNL device resets now consists of only calls up the stack
such as dev_close() and dev_open() that will result in NDO calls
to the driver. These will be handled with state changes from the
stack. Also, there is a problem of the dev_close and dev_open
being blocked by checks for reset in progress also using the
ICE_DCBNL_DEVRESET bit.
Since the ICE_DCBNL_DEVRESET bit is not necessary for protecting
the driver from DCBNL device resets and it is actually blocking
changes coming from the DCBNL interface, remove the bit from the
PF state and don't block driver function based on DCBNL reset in
progress.

There is a possibility of race between ice_open or ice_stop calls
performed by OS and reset handling routine both trying to modify VSI
resources. Observed scenarios:
- reset handler deallocates memory in ice_vsi_free_arrays and ice_open
tries to access it in ice_vsi_cfg_txq leading to driver crash
- reset handler deallocates memory in ice_vsi_free_arrays and ice_close
tries to access it in ice_down leading to driver crash
- reset handler clears port scheduler topology and sets port state to
ICE_SCHED_PORT_STATE_INIT leading to ice_ena_vsi_txq fail in ice_open
To prevent this additional checks in ice_open and ice_stop are
introduced to make sure that OS is not allowed to alter VSI config while
reset is in progress.

iSCSI can use both TCP ports 860 and 3260. However, in our current
implementation, the ice_aqc_opc_get_cee_dcb_cfg (0x0A07) AQ command
doesn't provide a way to communicate the protocol port number to the
AQ's caller. Thus, we assume that 3260 is the iSCSI port number at the
AQ's caller layer.
Rely on the dcbx-willing mode, desired QoS and remote QoS configuration to
determine which port number that iSCSI will use.

Enable returning FDIR completion status by checking the
ctrl_vsi Rx queue descriptor value.
To enable returning FDIR completion status from ctrl_vsi Rx queue,
COMP_Queue and COMP_Report of FDIR filter programming descriptor
needs to be properly configured. After program request sent to ctrl_vsi
Tx queue, ctrl_vsi Rx queue interrupt will be triggered and
completion status will be returned.
Driver will first issue request in ice_vc_fdir_add_fltr(), then
pass FDIR context to the background task in interrupt service routine
ice_vc_fdir_irq_handler() and finally deal with them in
ice_flush_fdir_ctx(). ice_flush_fdir_ctx() will check the descriptor's
value, fdir context, and then send back virtual channel message to VF
by calling ice_vc_add_fdir_fltr_post(). An additional timer will be
setup in case of hardware interrupt timeout.

The virtual channel is going to be extended to support FDIR and
RSS configure from AVF. New data structures and OP codes will be
added, the patch enable the FDIR part.
To support above advanced AVF feature, we need to figure out
what kind of data structure should be passed from VF to PF to describe
an FDIR rule or RSS config rule. The common part of the requirement is
we need a data structure to represent the input set selection of a rule's
hash key.
An input set selection is a group of fields be selected from one or more
network protocol layers that could be identified as a specific flow.
For example, select dst IP address from an IPv4 header combined with
dst port from the TCP header as the input set for an IPv4/TCP flow.
The patch adds a new data structure virtchnl_proto_hdrs to abstract
a network protocol headers group which is composed of layers of network
protocol header(virtchnl_proto_hdr).
A protocol header contains a 32 bits mask (field_selector) to describe
which fields are selected as input sets, as well as a header type
(enum virtchnl_proto_hdr_type). Each bit is mapped to a field in
enum virtchnl_proto_hdr_field guided by its header type.
+------------+-----------+------------------------------+
| | Proto Hdr | Header Type A |
| | +------------------------------+
| | | BIT 31 | ... | BIT 1 | BIT 0 |
| |-----------+------------------------------+
|Proto Hdrs | Proto Hdr | Header Type B |
| | +------------------------------+
| | | BIT 31 | ... | BIT 1 | BIT 0 |
| |-----------+------------------------------+
| | Proto Hdr | Header Type C |
| | +------------------------------+
| | | BIT 31 | ... | BIT 1 | BIT 0 |
| |-----------+------------------------------+
| | .... |
+-------------------------------------------------------+
All fields in enum virtchnl_proto_hdr_fields are grouped with header type
and the value of the first field of a header type is always 32 aligned.
enum proto_hdr_type {
header_type_A = 0;
header_type_B = 1;
....
}
enum proto_hdr_field {
/* header type A */
header_A_field_0 = 0,
header_A_field_1 = 1,
header_A_field_2 = 2,
header_A_field_3 = 3,
/* header type B */
header_B_field_0 = 32, // = header_type_B << 5
header_B_field_0 = 33,
header_B_field_0 = 34
header_B_field_0 = 35,
....
};
So we have:
proto_hdr_type = proto_hdr_field / 32
bit offset = proto_hdr_field % 32
To simply the protocol header's operations, couple help macros are added.
For example, to select src IP and dst port as input set for an IPv4/UDP
flow.
we have:
struct virtchnl_proto_hdr hdr[2];
VIRTCHNL_SET_PROTO_HDR_TYPE(&hdr[0], IPV4)
VIRTCHNL_ADD_PROTO_HDR_FIELD(&hdr[0], IPV4, SRC)
VIRTCHNL_SET_PROTO_HDR_TYPE(&hdr[1], UDP)
VIRTCHNL_ADD_PROTO_HDR_FIELD(&hdr[1], UDP, DST)
The byte array is used to store the protocol header of a training package.
The byte array must be network order.
The patch added virtual channel support for iAVF FDIR add/validate/delete
filter. iAVF FDIR is Flow Director for Intel Adaptive Virtual Function
which can direct Ethernet packets to the queues of the Network Interface
Card. Add/delete command is adding or deleting one rule for each virtual
channel message, while validate command is just verifying if this rule
is valid without any other operations.
To add or delete one rule, driver needs to config TCAM and Profile,
build training packets which contains the input set value, and send
the training packets through FDIR Tx queue. In addition, driver needs to
manage the software context to avoid adding duplicated rules, deleting
non-existent rule, input set conflicts and other invalid cases.
NOTE:
Supported pattern/actions and their parse functions are not be included in
this patch, they will be added in a separate one.

We are going to enable FDIR configure for AVF through virtual channel.
The first step is to add helper functions to support control VSI setup.
A control VSI will be allocated for a VF when AVF creates its
first FDIR rule through ice_vf_ctrl_vsi_setup().
The patch will also allocate FDIR rule space for VF's control VSI.
If a VF asks for flow director rules, then those should come entirely
from the best effort pool and not from the guaranteed pool. The patch
allow a VF VSI to have only space in the best effort rules.

We want to change the current ndo_xdp_xmit drop semantics because it will
allow us to implement better queue overflow handling. This is working
towards the larger goal of a XDP TX queue-hook. Move XDP_REDIRECT error
path handling from each XDP ethernet driver to devmap code. According to
the new APIs, the driver running the ndo_xdp_xmit pointer, will break tx
loop whenever the hw reports a tx error and it will just return to devmap
caller the number of successfully transmitted frames. It will be devmap
responsibility to free dropped frames.
Move each XDP ndo_xdp_xmit capable driver to the new APIs:
- veth
- virtio-net
- mvneta
- mvpp2
- socionext
- amazon ena
- bnxt
- freescale (dpaa2, dpaa)
- xen-frontend
- qede
- ice
- igb
- ixgbe
- i40e
- mlx5
- ti (cpsw, cpsw-new)
- tun
- sfc

Update the Intel drivers to make use of ethtool_sprintf. The general idea
is to reduce code size and overhead by replacing the repeated pattern of
string printf statements and ETH_STRING_LEN counter increments.

Optimize ice_run_xdp_zc() for the XDP program verdict being
XDP_REDIRECT in the xsk zero-copy path. This path is only used when
having AF_XDP zero-copy on and in that case most packets will be
directed to user space. This provides a little over 100k extra packets
in throughput on my server when running l2fwd in xdpsock.

ice_rx_offset(), that is supposed to initialize the Rx buffer headroom,
relies on ICE_RX_FLAGS_RING_BUILD_SKB flag as well as XDP prog presence.
Currently, the callsite of mentioned function is placed incorrectly
within ice_setup_rx_ring() where Rx ring's build skb flag is not
set yet. This causes the XDP_REDIRECT to be partially broken due to
inability to create xdp_frame in the headroom space, as the headroom is
0.
Fix this by moving ice_rx_offset() to ice_setup_rx_ctx() after the flag
setting.

Fix the wrong napi work done reporting in the xsk path of the ice
driver. The code in the main Rx processing loop was written to assume
that the buffer allocation code returns true if all allocations where
successful and false if not. In contrast with all other Intel NIC xsk
drivers, the ice_alloc_rx_bufs_zc() has the inverted logic messing up
the work done reporting in the napi loop.
This can be fixed either by inverting the return value from
ice_alloc_rx_bufs_zc() in the function that uses this in an incorrect
way, or by changing the return value of ice_alloc_rx_bufs_zc(). We
chose the latter as it makes all the xsk allocation functions for
Intel NICs behave in the same way. My guess is that it was this
unexpected discrepancy that gave rise to this bug in the first place.
Fixes: 5bb0c4b5eb61 ("ice, xsk: Move Rx allocation out of while-loop")
