The configuration/command below is failing when the VF in the xml

error: Cannot set interface MAC/vlanid to 00🇩🇪ad:00:11:01/0 for
ifname ens1f1 vf 0: Device or resource busy
This is failing because the VF has not been completely removed/reset
after being unbound (via the virsh command above) from the host iavf
driver and ice_set_vf_mac() checks if the VF is disabled before waiting
for the reset to finish.
Fix this by waiting for the VF remove/reset process to happen before
checking if the VF is disabled. Also, since many functions for VF
administration on the PF were more or less calling the same 3 functions
(ice_wait_on_vf_reset(), ice_is_vf_disabled(), and ice_check_vf_init())
move these into the helper function ice_check_vf_ready_for_cfg(). Then
call this function in any flow that attempts to configure/query a VF
from the PF.
Lastly, increase the maximum wait time in ice_wait_on_vf_reset() to
800ms, and modify/add the #define(s) that determine the wait time.
This was done for robustness because in rare/stress cases VF removal can
take a max of ~800ms and previously the wait was a max of ~300ms.

Each extracted frame on Ocelot has an IFH. The frame and IFH are extracted
by reading chuncks of 4 bytes from a register.
In case the IFH and frames were read corretly it would try to read the next
frame. In case there are no more frames in the queue, it checks if there
were any previous errors and in that case clear the queue. But this check
will always succeed also when there are no errors. Because when extracting
the IFH the error is checked against 4(number of bytes read) and then the
error is set only if the extraction of the frame failed. So in a happy case
where there are no errors the err variable is still 4. So it could be
a case where after the check that there are no more frames in the queue, a
frame will arrive in the queue but because the error is not reseted, it
would try to flush the queue. So the frame will be lost.
The fix consist in resetting the error after reading the IFH.

This driver is mixing 8-bit and 16-bit bus accessors for reasons unknown,
however the speculation is that this was some sort of attempt to support
the 8-bit bus mode.
As per the KS8851-16MLL documentation, all two registers accessed via the
8-bit accessors are internally 16-bit registers, so reading them using
16-bit accessors is fine. The KS_CCR read can be converted to 16-bit read
outright, as it is already a concatenation of two 8-bit reads of that
register. The KS_RXQCR accesses are 8-bit only, however writing the top
8 bits of the register is OK as well, since the driver caches the entire
16-bit register value anyway.
Finally, the driver is not used by any hardware in the kernel right now.
The only hardware available to me is one with 16-bit bus, so I have no
way to test the 8-bit bus mode, however it is unlikely this ever really
worked anyway. If the 8-bit bus mode is ever required, it can be easily
added by adjusting the 16-bit accessors to do 2 consecutive accesses,
which is how this should have been done from the beginning.

It turns out there's an easy way to get packets queued up while still
having an MTU of zero, and that's via persistent keep alive. This commit
makes sure that in whatever condition, we don't wind up dividing by
zero. Note that an MTU of zero for a wireguard interface is something
quasi-valid, so I don't think the correct fix is to limit it via
min_mtu. This can be reproduced easily with:
ip link add wg0 type wireguard
ip link add wg1 type wireguard
ip link set wg0 up mtu 0
ip link set wg1 up
wg set wg0 private-key <(wg genkey)
wg set wg1 listen-port 1 private-key <(wg genkey) peer $(wg show wg0 public-key)
wg set wg0 peer $(wg show wg1 public-key) persistent-keepalive 1 endpoint 127.0.0.1:1
However, while min_mtu=0 seems fine, it makes sense to restrict the
max_mtu. This commit also restricts the maximum MTU to the greatest
number for which rounding up to the padding multiple won't overflow a
signed integer. Packets this large were always rejected anyway
eventually, due to checks deeper in, but it seems more sound not to even
let the administrator configure something that won't work anyway.
We use this opportunity to clean up this function a bit so that it's
clear which paths we're expecting.

Yet another checksum offload compatibility issue was found.
The known issue is that AQC HW marks tcp packets with 0xFFFF checksum
as invalid (1). This is workarounded in driver, passing all the suspicious
packets up to the stack for further csum validation.
Another HW problem (2) is that it hides invalid csum of LRO aggregated
packets inside of the individual descriptors. That was workarounded
by forced scan of all LRO descriptors for checksum errors.
However the scan logic was joint for both LRO and multi-descriptor
packets (jumbos). And this causes the issue.
We have to drop LRO packets with the detected bad checksum
because of (2), but we have to pass jumbo packets to stack because of (1).
When using windows tcp partner with jumbo frames but with LSO disabled
driver discards such frames as bad checksummed. But only LRO frames
should be dropped, not jumbos.
On such a configurations tcp stream have a chance of drops and stucks.

new functions continue doing the right thing in the context of
wireguard. It does this by setting up a condition that will definately
evoke an icmp error message from the driver, but along a nat'd path.

Because sunvnet is calling icmp from network device context, it should use
the ndo helper so that the rate limiting applies correctly. While we're
at it, doing the additional route lookup before calling icmp_ndo_send is
superfluous, since this is the job of the icmp code in the first place.

1. Remove local variable num_q_vectors and use vsi->num_q_vectors instead
2. Remove local variable pf and pass vsi->back to ice_pf_to_dev

Formatting strings in print function calls (like dev_info, dev_err, etc.)
can exceed 80 columns without making checkpatch unhappy. So remove
newlines where applicable and make print statements more compact.

Use ice_pf_to_dev(pf) instead of &pf->pdev->dev
Use ice_pf_to_dev(vsi->back) instead of &vsi->back->pdev->dev
When a pointer to the pf instance is available, use ice_pf_to_dev
instead of ice_hw_to_dev
