Lorenzo BianconiandFelix Fietkau 2d4b8f57cc mt76x2: mac: fix possible NULL pointer dereferencing in mt76x2_mac_write_txwi()

Lorenzo BianconiandFelix Fietkau ca5ca8c779 mt76x2: fix possible NULL pointer dereferencing in mt76x2_ampdu_action() 
Initialize mt76_txq pointer after ieee80211_txq pointer check.
Remove space after the pointer cast

Colin Ian KingandFelix Fietkau cf4a5ce03d mt76: fix memcpy to potential null pointer on failed allocation 
Currently if the allocation of skb fails and returns NULL then the
call to skb_put will cause a null pointer dereference. Fix this by
checking for a null skb and returning NULL.  Note that calls to
function mt76x2_mcu_msg_alloc don't directly check the null return
but instead pass the NULL pointer to mt76x2_mcu_msg_send which
checks for the NULL and returns ENOMEM in this case.

Detected by CoverityScan, CID#1462624 ("Dereference null return value")

Fixes: 7bc04215a66b ("mt76: add driver code for MT76x2e")

Lorenzo BianconiandFelix Fietkau ac815fa2a5 mt76x2: init: fix rx filter default value during init 
mt76x2_mac_start writes dev->rxfilter to the hardware. It also happens
during init, before dev->rxfilter is filled with the initval register
value, leading to issues like promisc mode being enabled
unconditionally.

Fix this by reading the default value into dev->rxfilter earlier

Felix Fietkau c64633e857 mt76x2: configure rx filter based on monitor mode setting 
Due to an unrelated issue, the MT_RX_FILTR_CFG_PROMISC flag is currently
unset, which means that monitor mode is unconditionally enabled.
Toggle this flag based on the mac80211 monitor mode setting instead

Felix Fietkau 792859b237 mt76x2: fix transmission of encrypted management frames 
Hardware encryption seems to break encrypted unicast mgmt tx.
Unfortunately the hardware TXWI header does not have a bit to indicate
that a frame is software encrypted, so sw-encrypted frames need to use a
different WCID. For that to work, the CCMP PN needs to be generated in
software, which makes things a bit slower, so only do it for keys that
also need to tx management frames.
