2020-12-10iwlwifi: mvm: purge the BSS table upon firmware loadEmmanuel Grumbach
When the firmware is loaded, its internal timer (GP2) is reset and all the time_sync in the BSS table is now unusable. Ask cfg80211 to purge the BSS table.

2020-12-10iwlwifi: support firmware reset handshakeJohannes Berg
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).

2020-12-10iwlwifi: mvm: fix a race in CSA that caused assert 0x3420Sara Sharon
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.

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

2020-12-10iwlwifi: copy iwl_he_capa for modificationsJohannes Berg
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.

2020-12-10iwlwifi: pcie: remove obsolete pre-release support codeEmmanuel Grumbach
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.

The NO_160 flag specifies if the device doesn't have 160 MHz support, but we errorneously assumed the opposite. If the flag was set, we were considering that 160 MHz was supported, but it's actually the opposite. Fix it by inverting the bits, i.e. NO_160 is 0x1 and 160 is 0x0.

2020-11-10iwlwifi: mvm: fix kernel panic in case of assert during CSASara Sharon
During CSA, we briefly nullify the phy context, in __iwl_mvm_unassign_vif_chanctx. In case we have a FW assert right after it, it remains NULL though. We end up running into endless loop due to mac80211 trying repeatedly to move us to ASSOC state, and we keep returning -EINVAL. Later down the road we hit a kernel panic. Detect and avoid this endless loop.
