27eeb03784 iwlwifi: mvm: add size checks for range response notification 
The range response notification has several versions. Check the
notification size according to the expected notification version.
Notifications with incorrect size will be ignored.

b8aba27cdc iwlwifi: tighten RX MPDU bounds checks 
Previously, we added checks that the contained MPDU size is long
enough, but really we should also check that the notification
itself fits into the data. Add some checks for that.

Also add unlikely() annotations on the previously added checks.

906d4eb844 iwlwifi: support firmware reset handshake 
There are some races in the hardware that can possibly lead to
a bus lockup later during a restart when we manage to kill the
firmware at a bad time (while it's accessing the bus).

To work around this, add support for a new handshake between
firmware and driver to ensure that the firmware is in a well-
known state before we kill it.

caf4637712 iwlwifi: mvm: fix a race in CSA that caused assert 0x3420 
When we get a channel switch with a very long quiet period, we schedule
a work to disconnect after a while. This work runs in background. In the
meanwhile, we keep getting beacons and sending FW modify command for each.
This has a potential race, where we modify the CSA after we aborted it.

Protect the flow by setting csa_failed to true in case we abort, and check
it before sending the modify command.

This required a modification to the way we treat csa_failed in
iwl_mvm_post_channel_switch:
1. The variable isn't being reset anymore, so we can still look at it in
iwl_mvm_channel_switch_rx_beacon. This is fine, since we reset it when
starting a new CSA.
2. There is no more early return in case of csa_failed. This is fine,
since before this patch csa_failed was set only for GO, and for GO the
function is only resetting the power settings, which we want to restore
even in case of failure.

However, as we never had any complaints about not printing

I suspect the code handling it was incorrectly anyway) just
remove the code for it.

The argument type to iwl_mvm_notify_rx_queue() is currently just
a u8 *, but that's misleading because we actually need the inner

interpret it when we get it back from the device (to check the
sync bool and possibly the cookie.)

Therefore, clear up any potential confusion and require that the
data passed is of type struct iwl_mvm_internal_rxq_notif *.

Also, while at it, rename the "count" to "notif_size" as "count"
doesn't really clearly say what it's counting.

d43ab298ef iwlwifi: copy iwl_he_capa for modifications 
This data is not necessarily the same across devices as we may
modify it due to the number of antennas and for overrides (though
in practice overrides are likely to be identical), so modifying
the global data is wrong.

Make a copy of it in the NVM data and modify it there instead.

4adfaf9b2d iwlwifi: pcie: remove obsolete pre-release support code 
We no longer need code that was introduced to differentiate
between two early versions of 8260.

We can remove this convoluted way to get the hardware version
that was needed because of a bug in the register's
configuration.

Moreover, since we no longer need to access the PRPH
registers, we no longer need to wake up the device,
request ownership, etc...
Remove all that.

This allows us to get the rid of the obsolete comment
about the AUX bus MISC address space which should have
been moved when this code was moved away from here.

9125abe7b9 vrf: handle CONFIG_IPV6 not set for vrf_add_mac_header_if_unset() 
The vrf_add_mac_header_if_unset() is defined within a conditional
compilation block which depends on the CONFIG_IPV6 macro.
However, the vrf_add_mac_header_if_unset() needs to be called also by IPv4
related code and when the CONFIG_IPV6 is not set, this function is missing.
As a consequence, the build process stops reporting the error:

 ERROR: implicit declaration of function 'vrf_add_mac_header_if_unset'

The problem is solved by *only* moving functions
vrf_add_mac_header_if_unset() and vrf_prepare_mac_header() out of the
conditional block.
