Add a private flag to expressly enable support for VF IPsec offload.
The VF will have to be "trusted" in order to use the hardware offload,
but because of the general concerns of managing VF access, we want to
be sure the user specifically is enabling the feature.
This is likely a candidate for becoming a netdev feature flag.

VLAN pruning is not valid when VLAN 0 is not active. If VLAN
pruning is enabled and VLAN 0 is not active (8021q driver not loaded)
then normal, non-VLAN, traffic will not pass.
TX/RX VLAN pruning is enabled when the VLAN 0 is added to the
active_vlan bitmap and it is disabled when VLAN 0 is removed from the
active_vlan bitmap.
So, only enable VLAN pruning when VLAN 0 is active. Setting RX VLAN
pruning causes the switch to drop received VLAN packets when there
are no matching VLAN ids in the associated VSI's switch filters. Setting
TX pruning makes it so the switch will not send out any packets with
VLAN tags that don't match the associated VSI's switch filters.
With this patch, if the VF or PF tries to send a VLAN tagged packet with
a VLAN tag that it does not have a pruning rule for it will trigger an
MDD event. For example, if PF0 has VLAN10 and VLAN11 interfaces and
scapy is used to send a packet with VLAN8 then the MDD is triggered.
Also make ice_vsi_kill_vlan return a value which the caller can check
before updating VLAN related data structures (counts, pruning bits, etc.).

When a malicious operation is detected, the firmware triggers an
interrupt, which is then picked up by the service task (specifically by
ice_handle_mdd_event). A reset is scheduled if required.
Tx hang detection works in a similar way, except the logic here monitors
the VSI's Tx queues and tries to revive them if stalled. If the hang is
not resolved, the kernel eventually calls ndo_tx_timeout, which is
handled by ice_tx_timeout.

This patch refactors aspects of the VSI allocation, deletion and rebuild
flow. Some of the more noteworthy changes are described below.
1) On reset, all switch filters applied in the hardware are lost. In
the rebuild flow, only MAC and broadcast filters are being restored.
Instead, use a new function ice_replay_all_fltr to restore all the
filters that were previously added. To do this, remove calls to
ice_remove_vsi_fltr to prevent cleaning out the internal bookkeeping
structures that ice_replay_all_fltr uses to replay filters.
2) Introduce a new state bit __ICE_PREPARED_FOR_RESET to distinguish the
PF that requested the reset (and consequently prepared for it) from
the rest of the PFs. These other PFs will prepare for reset only
when they receive an interrupt from the firmware.
3) Use new functions ice_add_vsi and ice_free_vsi to create and destroy
VSIs respectively. These functions accept a handle to uniquely
identify a VSI. This same handle is required to rebuild the VSI post
reset. To prevent confusion, the existing ice_vsi_add was renamed to
ice_vsi_init.
4) Enhance ice_vsi_setup for the upcoming SR-IOV changes and expose a
new wrapper function ice_pf_vsi_setup to create PF VSIs. Rework the
error handling path in ice_setup_pf_sw.
5) Introduce a new function ice_vsi_release_all to release all PF VSIs.

Once reset is issued, the driver loses all control queue interfaces.
Exercising control queue operations during reset is incorrect and
may result in long timeouts.
This patch introduces a new field 'reset_ongoing' in the hw structure.
This is set to 1 by the core driver when it receives a reset interrupt.
ice_sq_send_cmd checks reset_ongoing before actually issuing the control
queue operation. If a reset is in progress, it returns a soft error code
(ICE_ERR_RESET_PENDING) to the caller. The caller may or may not have to
take any action based on this return. Once the driver knows that the
reset is done, it has to set reset_ongoing back to 0. This will allow
control queue operations to be posted to the hardware again.
This "bail out" logic was specifically added to ice_sq_send_cmd (which
is pretty low level function) so that we have one solution in one place
that applies to all types of control queues.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This issue was detected with the help of Coccinelle.

When running in AP mode, ath10k sometimes suffers from TX credit
starvation. The issue is hard to reproduce and shows up once in a
few days, but has been repeatedly seen with QCA9882 and a large
range of firmwares, including 10.2.4.70.67.
Once the module is in this state, TX credits are never replenished,
which results in "SWBA overrun" errors, as no beacons can be sent.
Even worse, WMI commands run in a timeout while holding the conf
mutex for three seconds each, making any further operations slow
and the whole system unresponsive.
The firmware/driver never recovers from that state automatically,
and triggering TX flush or warm restarts won't work over WMI. So
issue a hardware restart if a WMI command times out due to missing
TX credits. This implies a connectivity outage of about 1.4s in AP
mode, but brings back the interface and the whole system to a usable
state. WMI command timeouts have not been seen in absent of this
specific issue, so taking such drastic actions seems legitimate.

This will prevent accessing any other PHYs for other Ethernet MACs on

macb_init_hw() is called from macb_open() which sets the MPE bit again.
I.e. currently the MDIO bus has a short disruption at open time and is
