This fixes issue with interface bridging. Linux bridging sets promiscuous mode for all interfaces that are in a bridge. This translates to configure_filter() being called in a mac80211 driver. Before the patch operational interface would be started and upped again when promiscuous mode was enabled causing all sorts of strange issues: * no HTT RX happening (i.e. no traffic) * FW crash upon driver reload/unload Signed-off-by: NMichal Kazior <michal.kazior@tieto.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

ath10k_bss_assoc() was calling ath10k_peer_assoc(), which can sleep, under atomic rcu_read_lock() and causing scheduing while atomic errors. Workaround that by delaying the call to ath10k_wmi_peer_assoc(). Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

mac80211 interface iteration functions that were used originally iterated over interfaces that weren't re-added to the driver during recovery. Since internal vif list is now used it's safe to remove the safe-guard as internal vif list is based on add/remove_interface function which guarantees that vdev is created in FW before it is iterated over.

Recent HTC/WMI changes introduced the bug. ath10k was using _atomic iteration function with sleepable functions. mac80211 provides another iteration function but it cannot be safely called in hw_config() callback due to local->iflist_mtx being possibly acquired already. The patch uses internal vif list for iteration purposes and removes/refactors no longer necessary _iter functions.

Recent WMI/HTC changes made it possible for WMI commands to sleep (if there's not enough HTC TX credits to submit a command). TX path is in an atomic context so calling WMI commands in it is wrong. This simply moves WEP key index update to a worker and fixes the 'scheduling while atomic' bug. This still leaves multiple WEP key handling laggy, i.e. some frames may be TXed with an old/different key (although recipient should still be able to RX them). kvalo: changed the title Signed-off-by: NMichal Kazior <michal.kazior@tieto.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

For VHT peers, the maximum A-MPDU size has to be calculated from the VHT capabilities element and not the HT-cap. The formula is the same, but a higher value is used in VHT, allowing larger aggregates to be transmitted. The patch contains a workaround for some Netgear/Linksys APs that report Rx A-MPDU factor incorrectly.

Both firmwares (main and 10.x) have different set of vdev parameters.

This is still the only way to submit mgmt frames in case of 10.X firmware. This patch introduces wmi_mgmt_tx queue, because of the fact WMI command can block. This is a problem for ath10k_tx_htt(), since it's called from atomic context. The skb queue and worker are introduced to move the mgmt frame handling out of .tx callback context and not block.

Until now the all MSDU transfer related structures were freed when all resources were unreferenced. Now HTC transfer is freed independently and HTT transfer is so too. This yields a way more simpler ath10k_skb_cb and should possibly enable parallel pipe processing (which is now serialized in ath10k_pci_process_ce routine).

New firmware comes with new HTT protocol version. In 3.0 the separate mgmt tx command has been removed.
