The functions that are used for PF VSI/netdev setup will also be used
for SR-IOV support. To allow reuse of these functions, move these
functions out of ice_main.c to ice_common.c/ice_lib.c
This move is done across multiple patches. Each patch moves a few
functions and may have minor adjustments. For example, a function that was
previously static in ice_main.c will be made non-static temporarily in
its new location to allow the driver to build cleanly. These adjustments
will be removed in subsequent patches where more code is moved out of
ice_main.c
In this particular patch, the following functions were moved out of
ice_main.c:
int ice_add_mac_to_list
ice_free_fltr_list
ice_stat_update40
ice_stat_update32
ice_update_eth_stats
ice_vsi_add_vlan
ice_vsi_kill_vlan
ice_vsi_manage_vlan_insertion
ice_vsi_manage_vlan_stripping

The system image guid is a read-only field which is used by the TC
offloads code to determine if two mlx5 devices belong to the same
ASIC while adding flows.
Read this once and save it on the core device rather than querying each

Increased the amount of channels the representors can open to be the
amount of CPUs. The default amount opened remains one.
Used the standard NIC netdev functions to:
* Set RSS params when building the representors' params.
* Setup an indirect TIR and RQT for the representors upon
initialization.
* Create a TTC flow table for the representors' indirect TIR (when
creating the TTC table, mlx5e_set_ttc_basic_params() is not called,
in order to avoid setting the inner_ttc param, which is not needed).
Added ethtool control to the representors for setting and querying
the amount of open channels. Additionally, included logic in the
representors' ethtool set channels handler which controls a
representor's vport rx rule, so that if there is one open channel
the rx rule steers traffic to the representor's direct TIR, whereas
if there is more than one channel, the rx rule steers traffic to the
new TTC flow table.

Enabled checksum and TSO offloads for the representors, in
order to increase their performance, which is required to
increase the performance of flows that cannot be offloaded.
Checksum offloads contribute to a general acceleration of all
traffic (to around 150%), whereas the TSO offload contributes
to a prominent acceleration of the representor's TX for traffic
flows with larger than MTU sized packets (to around 200%). This
is the usual case for TCP streams, as the PF, which serves as
the uplink representor, and the VF representors employ GRO before
forwarding the packets to the representor.
GRO was enabled implicitly for the representors beforehand, and
is explicitly enabled here to ensure that the representors preserve
the performance boost it provides (of around 200%) when working in
tandem with the TSO offload by the forwardee, which is the standard
case as both the PF and the VF representors employ HW TSO.
The impact of these changes can be seen in the following
measurements taken on a setup of a VM over a VF, connected
to OVS via the VF representor, to an external host:
Before current changes:
TCP Throughput [Gb/s]
External host to VM ~ 10.5
VM to external host ~ 23.5
With just checksum offloads enabled:
TCP Throughput [Gb/s]
External host to VM ~ 14.9
VM to external host ~ 28.5
With the TSO offload also enabled:
TCP Throughput [Gb/s]
External host to VM ~ 30.5

The representors' RQ size was not large enough for them to achieve
high enough performance, and therefore needed to be enlarged, while
suffering a minimum hit to its memory usage. To achieve this the
representors RQ size was increased, and its type was changed to be a
striding RQ if it is supported.
Towards that goal the following changes were made:
* Extracted the sequence for setting the standard netdev's RQ parmas
into a function
* Replaced the sequence for setting the representor's RQ params with
the standard sequence
The impact of this change can be seen in the following measurements
taken on a setup of a VM over a VF, connected to OVS via the VF
representor, to an external host:
Before current change:
TCP Throughput [Gb/s]
VM to external host ~ 7.2
With the current change (measured with a striding RQ):
TCP Throughput [Gb/s]
VM to external host ~ 23.5

In flow steering, if asked to, the hardware matches on the first ethertype
which is not vlan. It's possible to set a rule as follows, which is meant
to match on untagged packet, but will match on a vlan packet:
tc filter add dev eth0 parent ffff: protocol ip flower ...
To avoid this for packets with single tag, we set vlan masks to tell
hardware to check the tags for every matched packet.

In regular NIC transmission flow, driver always configures MAC using
Tx queue zero descriptor as a part of MAC learning flow.
But with multi Tx queue supported NIC, regular transmission can occur on
any non-zero Tx queue and from that context it uses
Tx queue zero descriptor to configure MAC, at the same time TX queue
zero could be used by another CPU for regular transmission
which could lead to Tx queue zero descriptor corruption and cause FW
abort.
This patch fixes this in such a way that driver always configures
learned MAC address from the same Tx queue which is used for
regular transmission.

rx_mini_pending was set to an incorrect value. This was causing EINVAL to
always be returned to 'ethtool -G'. The driver does not support mini or
jumbo rings so the respective settings should be zero.
Also, change the valid range of the number of descriptors in the rings to
make the code simpler and easier for users to understand (this removes the
valid settings of 8 and 16). Add a system log message indicating when the
number is rounded-up from what the user specifies with the 'ethtool -G'
command (i.e. when it is not a multiple of 32), and update the log message
when a user-provided value is out of range to also indicate the stride.

We have MAX_FW_API_VER_BRANCH, MAX_FW_API_VER_MAJOR, and
MAX_FW_API_VER_MINOR that we use in ice_controlq.h to test when a
firmware version is newer than expected. This is currently tested by
comparing each field separately. Thus, we compare the branch field
against the MAX_FW_API_VER_BRANCH, and so forth.
This means that currently, if we suppose that the max firmware version
is defined as 0.2.1, i.e.
Then firmware 0.1.3 will fail to load. This is because the minor version
3 is greater than the max minor version 1.
This is not intuitive, because of the notion that increasing the major
firmware version to 2 should mean any firmware version with a major
version is less than 2 should be considered older than 2...
In order to allow both 0.2.1 and 0.1.3 to load, you would have to define
the "max" firmware version as 0.2.3.. It is possible that such
a firmware version doesn't even exist yet!
Fix this by replacing the current logic with an updated check that
behaves as follows:
First, we check the major version. If it is greater than the expected
version, then we prevent driver load. Additionally, a warning message is
logged to indicate to the system administrator that they need to update
their driver. This is now the only case where the driver will refuse to
load.
Second, if the major version is less than the expected version, we log
an information message indicating the NVM should be updated.
Third, if the major version is exact, we'll then check the minor
version. If the minor version is more than two versions less than
expected, we log an information message indicating the NVM should be
updated. If it is more than two versions greater than the expected
version, we log an information message that the driver should be
updated.
To support this, the ice_aq_ver_check function needs its signature
updated to pass the HW structure. Since we now pass this structure,
there is no need to pass the firmware API versions separately.

When shutting down the controlqs, we check if they are initialized
before we shut them down and destroy the lock. This is important, as it
prevents attempts to access the lock of an already shutdown queue.
Unfortunately, we checked rq.head and sq.head as the value to determine
if the queue was initialized. This doesn't work, because head is not
reset when the queue is shutdown. In some flows, the adminq will have
already been shut down prior to calling ice_shutdown_all_ctrlqs. This
can result in a crash due to attempting to access the already destroyed
mutex.
Fix this by using rq.count and sq.count instead. Indeed, ice_shutdown_sq
and ice_shutdown_rq already indicate that this is the value we should be
using to determine of the queue was initialized.

As diagnosed by Song Liu, ndo_poll_controller() can
be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC). This capture
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.
ibmvnic uses NAPI for TX completions, so we better let core
networking stack call the napi->poll() to avoid the capture.
ibmvnic_netpoll_controller() was completely wrong anyway,
as it was scheduling NAPI to service RX queues (instead of TX),
so I doubt netpoll ever worked on this driver.
