different from that in which the CRC is computed.
Rather than make two copies of the commands in two different orders,

mwifiex: disable TDLS link upon tear down event
This patch adds code to disable TDLS link upon reception of TDLS
teardown event from peer. Teardown event can happen either
because of TDLS teardown packet from peer or internal timeout
configured during TDLS setup. Event is propogated to cfg80211
so that userspace application can take appropriate action.

mwifiex: configure inactivity timeout for TDLS link
This patch adds configuration timeout for TDLS link. This is
configuered at the time of TDLS link configuration. If TDLS link
is inactive for more than timeout, FW will tear this link.

In case RFKILL is in KILL position, the NIC will issue an
interrupt straight away. This interrupt won't be sent
because it is masked in the hardware.
But if our interrupt service routine is called for another
reason (SHARED_IRQ), then we'll look at the interrupt cause
and service it. This can cause bad things if we are not
ready yet.
Explicitly clean the interrupt cause register to make sure
we won't service anything before we are ready to.

iwlwifi: mvm: fix sparse warning when _DEBUGFS isn't set
Since the declaration of iwl_mvm_fw_error_rxf_dump and
iwl_mvm_fw_error_sram_dump is under
ifdef CONFIG_IWLWIFI_DEBUGFS, do the same for their
implementation.
Publish WIPHY_FLAG_HAS_CHANNEL_SWITCH if the fw supports
newly introduced IWL_UCODE_TLV_API_CSA_FLOW.
When CSA starts, save the switching vif inside mvm and during the CSA period
configure fw with a new beacon after each beacon transmission in order to
update the csa counters.
Also, handle correctly the CSA unbind-bind flow which is triggered by mac80211
when the actual channel switch happens.

ath9k: Prevent divide-by-zero upon bad beacon_interval.
A similar patch fixed crashes seen on an ath9k system
when testing against a broken ath10k AP. This patch
is slightly less protective, but probably will do the
job and is less redundant.
