For security reasons, NIC firmware does not allow VF to set its VLAN if PF
set it already. Firmware allows VF to set its VLAN if PF did not set it.
After the VF instructs the firmware to set the VLAN, VF always indicates
(via return 0) that the operation is successful--even for the times when it
isn't.
Put in a mechanism for the VF's set VLAN function to receive the firmware
response code, then make that function return -EPERM if the firmware
forbids the operation.
Make that mechanism available for other functions that may, in the future,
be interested in receiving the response code from the firmware. That
mechanism involves adding new fields to struct octnic_ctrl_pkt, so make all
users of struct octnic_ctrl_pkt initialize the struct to zero before using
it; otherwise, the mechanism might act on uninitialized garbage.

On the case where nn->eth_port is null the warning message
is printing the port by dereferencing this null pointer.
Remove the deference to avoid a crash when printing the
warning message.

RX moderation default parameters shouldn't be set in
mlx5e_build_rx_cq_param since it would reset the values every time on
netdev open/close. Instead, it should be set in
mlx5e_set_rx_cq_mode_params which is called on driver load only.

Reuse the code for mlx5e_alloc_cq and mlx5e_alloc_drop_cq, as they
have a similar flow.
Prior to this patch, the CQEs in the "drop CQ" were not initialized,
fixed
it with the shared flow of alloc CQ. This is not a critical bug as the
RQ connected to this CQ never moved to RTS, but still better to have
this right.

In case an XDP program is attached, reserve XDP_PACKET_HEADROOM
bytes at the beginning of the packet for the program to play
with.
Modify the XDP logic in the driver to fill-in the missing bits
and re-calculate offsets and length after the program has finished
running to properly reflect the current status of the packet.
We can then go and remove the limitation of not supporting XDP programs
where xdp_adjust_head is set.

Driver currently doesn't support any headroom; The only 'available'
space it has in the head of the buffer is due to the placement
offset.
In order to allow [later] support of XDP adjustment of headroom,
modify the the ingress flow to properly handle a scenario where
the packets would have such.

Current implementation of VFs is very tight in regard to queue
resources. VFs support for XDP would require quite a bit of additional
infrastructure in qede and qed [sharing of queue-zones between queues,
more VF cids, mapping of the doorbell bar, etc.].
For now, prevent XDP programs from being attached to VFs.

Driver is currently using dma_unmap_single() with the address it
passed to device for the purpose of forwarding, but the XDP
transmission buffer was originally a page allocated for the rx-queue.
The mapped address is likely to differ from the original mapped
address due to the placement offset.
This difference is going to get even bigger once we support headroom.
Cache the original mapped address of the page, and use it for unmapping
of the buffer when completion arrives for the XDP forwarded packet.

Currently, each time an ingress packet is passed to networking stack
the driver increments a per-queue SW statistic.
As we want to have additional fields in the first cache-line of the
Rx-queue struct, change flow so this statistic would be updated once per
NAPI run. We will later push the statistic to a different cache line.

When the driver is removed or shut down, close any attached clients
(i.e. i40iw). This prevents a panic seen sometimes on forced driver
removal or system shutdown when iWarp is running.

This patch adds a capability negotiation between VF and PF using ENCAP/
ENCAP_CSUM offload flags in order for the VF to support outer checksum
and TSO offloads for encapsulated packets. These capabilities were assumed
by default and enabled in current hardware. Going forward, these features
needs to be negotiated with PF before advertising to the stack.
Additionally, strip out the mac.type checks for X722 since outer checksums
are enabled based on the ENCAP_CSUM offload negotiation flag and maintain
consistency between drivers in how the features are configured.

The HW incorrectly calculates the frame size without the vlan
tag and compares that against 64. It will thus flag 64-bytes
frames with a vlan tag as 60-bytes frames "runt" packets
which we'll then drop. Thus we end up dropping ARP packets
on vlan's ...
It does that whether vlan tag stripping is enabled or not.
This works around it by ignoring the "runt" error bit of the
frame has been vlan tagged and is at least 60 bytes.

The current driver receive path allocates pages and stashes
them into SKB fragments. This is not particularly useful as
we don't support jumbo frames (which wouldn't be great with
the small FIFOs on all the known implementations) anyway.
It also makes us flush the caches and allocate more memory
for RX than necessary.
So set our RX buf to our max packet size instead (which we
bump to 1536 bytes to account for packets with vlan tags
etc...) like most other ethernet drivers.
Then allocate skbs when populating the receive ring and DMA
directly into them.
This simplifies the RX path further.

We don't handle fragmented RX packets, so the "looping"
helpers to locate the first segment of a packet or to
drop a packet aren't actually helping.
Take them out and simplify ftgmac100_rx_packet() further

The fast path has a single unlikely() test for any error bit,
calling into a helper that sets the appropriate statistics.
The various netdev_info aren't particularly interesting. If
we want to differentiate the various length errors later we
can introduce driver specific stats using ethtool.

We can occasionally fail to allocate new RX buffers at
runtime or when starting the driver. At the moment the
latter just fails to open which is fine but the former
leaves stale DMA pointers in the ring.
Instead, use a scratch page and have all RX ring descriptors
point to it by default unless a proper buffer can be allocated.
It will help later on when re-initializing the whole ring
at runtime on link changes since there is no clean failure
path there unlike open().

We don't support jumbo frames, we will never receive a
fragmented packet, the RX buffer is always big enough,
if not then it's a runaway packet that can be dropped.
So take out the loop that handles such things in
ftgmac100_rx_packet() which will help with subsequent
simplifications and improvements to the RX path
