Improve reliability of the mailbox communication and remove
its potential flaws that may lead to the undefined or faulty behavior.
Recently some users reported issues on ESX with 10G Intel NICs which were
found to be caused by incorrect implementation of the PF-VF mailbox
communication.
Technical investigation highlighted areas to improve in the communication
between PF or VF that wants to send the message (sender) and the other
part which receives the message (receiver):
- Locking the mailbox when the sender wants to send a message
- Releasing the mailbox when the communication ends
- Returning the result of the mailbox message execution

Properly reconfigure VF VSIs after VF request ADQ.
Created new function to update queue mapping and queue pairs per TC
with AQ update VSI. This sets proper RSS size on NIC.
VFs num_queue_pairs should not be changed during setup of queue maps.
Previously, VF main VSI in ADQ had configured too many queues and had
wrong RSS size, which lead to packets not being consumed and drops in
connectivity.

Currently, the i40e_vsi_setup_queue_map is basing the count of queues in
TCs on a VSI's alloc_queue_pairs member which is not changed throughout
any user's action (for example via ethtool's set_channels callback).
This implies that vsi->tc_config.tc_info[n].qcount value that is given
to the kernel via netdev_set_tc_queue() that notifies about the count of
queues per particular traffic class is constant even if user has changed
the total count of queues.
This in turn caused the kernel warning after setting the queue count to
the lower value than the initial one:
$ ethtool -l ens801f0
Channel parameters for ens801f0:
Pre-set maximums:
RX: 0
TX: 0
Other: 1
Combined: 64
Current hardware settings:
RX: 0
TX: 0
Other: 1
Combined: 64
$ ethtool -L ens801f0 combined 40
[dmesg]
Number of in use tx queues changed invalidating tc mappings. Priority
traffic classification disabled!
Reason was that vsi->alloc_queue_pairs stayed at 64 value which was used
to set the qcount on TC0 (by default only TC0 exists so all of the
existing queues are assigned to TC0). we update the offset/qcount via
netdev_set_tc_queue() back to the old value but then the
netif_set_real_num_tx_queues() is using the vsi->num_queue_pairs as a
value which got set to 40.
Fix it by using vsi->req_queue_pairs as a queue count that will be
distributed across TCs. Do it only for non-zero values, which implies
that user actually requested the new count of queues.
For VSIs other than main, stay with the vsi->alloc_queue_pairs as we
only allow manipulating the queue count on main VSI.

net: make dev_watchdog() less intrusive
dev_watchdog() is used on many NIC to periodically monitor TX queues
to detect hangs.
Problem is : It stops all queues, then check them, then 'unfreeze' them.
Not only this stops feeding the NIC, it also migrates all qdiscs
to be serviced on the cpu calling netif_tx_unlock(), causing
a potential latency artifact.
With many TX queues, this is becoming more visible.

virtio_net_hdr_to_skb does not set the skb's gso_size and gso_type
correctly for UFO packets received via virtio-net that are a little over
the GSO size. This can lead to problems elsewhere in the networking
stack, e.g. ovs_vport_send dropping over-sized packets if gso_size is
not set.
This is due to the comparison
if (skb->len - p_off > gso_size)
not properly accounting for the transport layer header.
p_off includes the size of the transport layer header (thlen), so
skb->len - p_off is the size of the TCP/UDP payload.
gso_size is read from the virtio-net header. For UFO, fragmentation
happens at the IP level so does not need to include the UDP header.
Hence the calculation could be comparing a TCP/UDP payload length with
an IP payload length, causing legitimate virtio-net packets to have
lack gso_type/gso_size information.
Example: a UDP packet with payload size 1473 has IP payload size 1481.
If the guest used UFO, it is not fragmented and the virtio-net header's
flags indicate that it is a GSO frame (VIRTIO_NET_HDR_GSO_UDP), with
gso_size = 1480 for an MTU of 1500. skb->len will be 1515 and p_off
will be 42, so skb->len - p_off = 1473. Hence the comparison fails, and
shinfo->gso_size and gso_type are not set as they should be.
Instead, add the UDP header length before comparing to gso_size when
using UFO. In this way, it is the size of the IP payload that is
compared to gso_size.
