Currently, ipa_cmd_data_valid() is called by ipa_mem_config().
Nothing it does requires access to hardware though, so it can be
done during the init phase of IPA driver startup.
Create a new function ipa_cmd_init(), whose purpose is to do early
initialization related to IPA immediate commands. It will call the
build-time validation function, then will make the two calls made
previously by ipa_cmd_data_valid(). This make ipa_cmd_data_valid()
unnecessary, so get rid of it.
Rename ipa_cmd_header_valid() to be ipa_cmd_header_init_local_valid(),
so its name is clearer about which IPA immediate command it is
associated with.

We currently verify the table size and offset fit in the immediate
command fields that must encode them in ipa_table_valid_one(). We
can now make this check earlier, in ipa_table_mem_valid().
The non-hashed IPv4 filter and route tables will always exist, and
their sizes will match the IPv6 tables, as well as the hashed tables
(if supported). So it's sufficient to verify the offset and size of
the IPv4 non-hashed tables fit into these fields.
Rename the function ipa_cmd_table_init_valid(), to reinforce that
it is the TABLE_INIT immediate command fields we're checking.

Add checks in ipa_table_init() to ensure the memory regions defined
for IPA filter and routing tables are valid.
For routing tables, the checks ensure:
- The non-hashed IPv4 and IPv6 routing tables are defined
- The non-hashed IPv4 and IPv6 routing tables are the same size
- The number entries in the non-hashed IPv4 routing table is enough
to hold the number entries available to the modem, plus at least
one usable by the AP.
For filter tables, the checks ensure:
- The non-hashed IPv4 and IPv6 filter tables are defined
- The non-hashed IPv4 and IPv6 filter tables are the same size
- The number entries in the non-hashed IPv4 filter table is enough
to hold the endpoint bitmap, plus an entry for each defined
endpoint that supports filtering.
In addition, for both routing and filter tables:
- If hashing isn't supported (IPA v4.2), hashed tables are zero size
- If hashing *is* supported, all hashed tables are the same size as
their non-hashed counterparts.
When validating the size of routing tables, require the AP to have
at least one entry (in addition to those used by the modem).

There's no need to ensure table memory regions fit within the
IPA-local memory range. And there's no need to ensure the modem
header memory region is in range either. These are verified for all
memory regions in ipa_mem_size_valid(), once we have settled on the
size of IPA memory.

The entries in each IPA routing table are divided between the modem
and the AP. The modem always gets some number of entries located at
the base of the table; the AP gets all those that follow.
There's no reason to think the modem will use anything different
from the first entries in a routing table, so:
- Get rid of IPA_ROUTE_MODEM_MIN (just assume it's 0)
- Get rid of IPA_ROUTE_AP_MIN (just assume it's IPA_ROUTE_MODEM_COUNT)
And finally:
- Open-code IPA_ROUTE_AP_COUNT and remove its definition

This patch uses TC skbedit queue_mapping action to support
forwarding packets to a device queue. Such filters with action
forward to queue will be the highest priority switch filter in
HW.
Example:
$ tc filter add dev ens4f0 protocol ip ingress flower\
dst_ip 192.168.1.12 ip_proto tcp dst_port 5001\
action skbedit queue_mapping 5 skip_sw
The above command adds an ingress filter, incoming packets
qualifying the match will be accepted into queue 5. The queue
number is in decimal format.
Refactored ice_add_tc_flower_adv_fltr() to consolidate code with
action FWD_TO_VSI and FWD_TO QUEUE.

When a frame is sent using FDMA, the skb is mapped and then the mapped
address is given to an tx dcb that is different than the last used tx
dcb. Once the HW finish with this frame, it would generate an interrupt
and then the dcb can be reused and memory can be freed. For each dcb
there is an dcb buf that contains some meta-data(is used by PTP, is
it free). There is 1 to 1 relationship between dcb and dcb_buf.
The following issue was observed. That sometimes after changing the MTU
to allocate new tx dcbs and dcbs_buf, two frames were not
transmitted. The frames were not transmitted because when reloading the
tx dcbs, it was always presuming to use the first dcb but that was not
always happening. Because it could be that the last tx dcb used before
changing MTU was first dcb and then when it tried to get the next dcb it
would take dcb 1 instead of 0. Because it is supposed to take a
different dcb than the last used one. This can be fixed simply by
changing tx->last_in_use to -1 when the fdma is disabled to reload the
new dcb and dcbs_buff.
But there could be a different issue. For example, right after the frame
is sent, the MTU is changed. Now all the dcbs and dcbs_buf will be
cleared. And now get the interrupt from HW that it finished with the
frame. So when we try to clear the skb, it is not possible because we
lost all the dcbs_buf.
The solution here is to stop replacing the tx dcbs and dcbs_buf when
changing MTU because the TX doesn't care what is the MTU size, it is
only the RX that needs this information.

netif_stop_all_queues must be called before calling H_FREE_LOGICAL_LAN.
As a result, we can remove the pool_config field from the ibmveth
adapter structure.
Some device configuration changes call ibmveth_close in order to free
the current resources held by the device. These functions then make
their changes and call ibmveth_open to reallocate and reserve resources
for the device.
Prior to this commit, the flag pool_config was used to tell ibmveth_close
that it should not halt the transmit queue. pool_config was introduced in
commit 860f242eb534 ("[PATCH] ibmveth change buffer pools dynamically")
to avoid interrupting the tx flow when making rx config changes. Since
then, other commits adopted this approach, even if making tx config
changes.
The issue with this approach was that the hypervisor freed all of
the devices control structures after the hcall H_FREE_LOGICAL_LAN
was performed but the transmit queues were never stopped. So the higher
layers in the network stack would continue transmission but any
H_SEND_LOGICAL_LAN hcall would fail with H_PARAMETER until the
hypervisor's structures for the device were allocated with the
H_REGISTER_LOGICAL_LAN hcall in ibmveth_open. This resulted in
no real networking harm but did cause several of these error
messages to be logged: "h_send_logical_lan failed with rc=-4"
So, instead of trying to keep the transmit queues alive during network
configuration changes, just stop the queues, make necessary changes then
restart the queues.

This patch adds the support for configuring periodic output

and period.
For developers or testers, they can use the command "echo
<channel> <start.sec> <start.nsec> <period.sec> <period.
nsec> > /sys/class/ptp/ptp0/period" to specify time and
period to output PPS signal.
Notice that, the channel can only be set to 0. In addtion,
the start time must larger than the current PTP clock time.
So users can use the command "phc_ctl /dev/ptp0 -- get" to
get the current PTP clock time before.

Before 262f2b782e25 ("net: fman: Map the base address once"), the
physical address of the MAC was exposed to userspace in two places: via
sysfs and via SIOCGIFMAP. While this is not best practice, it is an
external ABI which is in use by userspace software.
The aforementioned commit inadvertently modified these addresses and
made them virtual. This constitutes and ABI break. Additionally, it
leaks the kernel's memory layout to userspace. Partially revert that
commit, reintroducing the resource back into struct mac_device, while
keeping the intended changes (the rework of the address mapping).

This adds rule encoding functionality to the VCAP API.
A rule consists of keys and actions in separate cache sections.
The maximum size of the keyset or actionset determines the size of the
rule.
The VCAP hardware need to be able to distinguish different rule sizes from
each other, and for that purpose some extra typegroup bits are added to the
rule when it is encoded.
The API provides a bit stream iterator that allows highlevel encoding
functionality to add key and action value bits independent of typegroup
bits.
This is handled by letting the concrete VCAP model provide the typegroup
table for the different rule sizes.
After the key and action values have been added to the encoding bit streams
the typegroup bits are set to their correct values just before the rule is
written to the VCAP hardware.
The key and action offsets provided in the VCAP model are the offset before
adding the typegroup bits.

This provides most of the rule handling needed to add a new rule to a VCAP.
To add a rule a client must follow these steps:
1) Allocate a new rule (provide an id or get one automatically assigned)
2) Add keys to the rule
3) Add actions to the rule
4) Optionally set a keyset on the rule
5) Optionally set an actionset on the rule
6) Validate the rule (this will add keyset and actionset if not specified
in the previous steps)
7) Add the rule (if the validation was successful)
8) Free the rule instance (a copy has been added to the VCAP)
The validation step will fail if there are no keysets with the requested
keys, or there are no actionsets with the requested actions.
The validation will also fail if the keyset is not configured for the port
for the requested protocol).

This provides a default port keyset configuration for the Sparx5 IS2 VCAP
where all ports and all lookups in IS2 use the same keyset (MAC_ETYPE) for
all types of traffic.
This means that no matter what frame type is received on any front port it
will generate the MAC_ETYPE keyset in the IS VCAP and any rule in the IS2
VCAP that uses this keyset will be matched against the keys in the
MAC_ETYPE keyset.
The callback interface used by the VCAP API is populated with Sparx5
specific handler functions that takes care of the actual reading and
writing to data to the Sparx5 IS2 VCAP instance.
A few functions are also added to the VCAP API to support addition of rule
fields such as the ingress port mask and the lookup bit.
The IS2 VCAP in Sparx5 is really divided in two instances with lookup 0
and 1 in the first instance and lookup 2 and 3 in the second instance.
The lookup bit selects lookup 0 or 3 in the respective instance when it is
set.

This adds initial TC flower filter support to Sparx5 for the IS2 VCAP.
The support consists of the source and destination MAC addresses,
and the trap and pass actions.
This is how you can create a rule that test the functionality:
tc qdisc add dev eth0 clsact
tc filter add dev eth0 ingress chain 8000000 prio 10 handle 10 \
protocol all flower skip_sw \
dst_mac 0a:0b:0c:0d:0e:0f \
src_mac 2:0:0:0:0:1 \
action trap
The IS2 chains in Sparx5 are assigned like this:
- chain 8000000: IS2 Lookup 0
- chain 8100000: IS2 Lookup 1
- chain 8200000: IS2 Lookup 2
- chain 8300000: IS2 Lookup 3

This provides the initial VCAP API framework and Sparx5 specific VCAP
implementation.
When the Sparx5 Switchdev driver is initialized it will also initialize its
VCAP module, and this hooks up the concrete Sparx5 VCAP model to the VCAP
API, so that the VCAP API knows what VCAP instances are available.

Support hardware offload when tunnel neigh out port is bond.
These feature work with the nfp firmware. If the firmware
supports the NFP_FL_FEATS_TUNNEL_NEIGH_LAG feature, nfp driver
write the bond information to the firmware neighbor table or
do nothing for bond. when neighbor MAC changes, nfp driver
need to update the neighbor information too.

For apollolake the mapping between LEDs and GPIO pins was off because of
a refactoring when we introduced a new device model.
In addition to the reordering the indices in the lookup table need to be

commit b0c07116c894 ("platform/x86: amd-pmc: Avoid reading SMU version at
probe time") adjusted the behavior for amd-pmc to avoid reading the SMU
version at startup but rather on first use to improve boot time.
However the SMU version is also used to decide whether to place a timer
based wakeup in the OS_HINT message. If the idlemask hasn't been read
before this message was sent then the SMU version will not have been
cached.
Ensure the SMU version has been read before deciding whether or not to
run this codepath.
