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.

Remove the reason of null pointer dereference in sync VSI filters.

There is a use case that the local and remote VTEPs are in the same
host. Currently, the out ifindex is not specified when looking up the
decap route for offloads. So in this case, a local route is returned
and the route dev is lo.
Actual tunnel interface can be created with a parameter "dev" [1],
which specifies the physical device to use for tunnel endpoint
communication. Pass this parameter to driver when looking up decap
route for offloads. So that a unicast route will be returned.

The recent addition of timestamp correction to compensate the CDC error
introduced a subtle signed/unsigned bug in stmmac_get_tx_hwtstamp() while
it managed for some obscure reason to avoid that in stmmac_get_rx_hwtstamp().
The issue is:
s64 adjust = 0;
u64 ns;
adjust += -(2 * (NSEC_PER_SEC / priv->plat->clk_ptp_rate));
ns += adjust;
works by chance on 64bit, but falls apart on 32bit because the compiler
knows that adjust fits into 32bit and then treats the addition as a u64 +
u32 resulting in an off by ~2 seconds failure.
The RX variant uses an u64 for adjust and does the adjustment via
ns -= adjust;
because consistency is obviously overrated.
Get rid of the pointless zero initialized adjust variable and do:
ns -= (2 * NSEC_PER_SEC) / priv->plat->clk_ptp_rate;
which is obviously correct and spares the adjust obfuscation. Aside of that
it yields a more accurate result because the multiplication takes place
before the integer divide truncation and not afterwards.
Stick the calculation into an inline so it can't be accidentally
disimproved. Return an u32 from that inline as the result is guaranteed
to fit which lets the compiler optimize the substraction.

With L1.2 disabled (and L1 + L1.1 active) everything is fine.
See also [0]. Can't test this, but L1 + L1.1 being active should be
sufficient to reach higher package power saving states.
