To: johannes; +Cc: linux-wireless, Daniel Gabay, Johannes Berg
From: Daniel Gabay <daniel.gabay@intel.com>
As described in IEEE sta 802.11-2020, table 9-30 (Address
field contents), A-MSDU address 3 should contain the BSSID
address.
In TX_CMD we copy the MAC header from skb, and skb address 3
holds the destination address, but it may not be identical to
the BSSID.
Using the wrong destination address appears to work with (most)
receivers without MLO, but in MLO some devices are checking for
it carefully, perhaps as a consequence of link to MLD address
translation.
Replace address 3 in the TX_CMD MAC header with the correct
address while retaining the skb address 3 unchanged.
This ensures that skb address 3 will be utilized later for
constructing the A-MSDU subframes.
Note that we fill in the MLD address, but the firmware will do the
necessary translation to link address after encryption.

Change it to send the cmd for all active links of the vif

in BZ, the mac step is not updated to the HW REV CSR.
For BZ-I, read it from the CNVI aux register
For BZ-U always take B step.

Before sending a SESSION PROTECTION cmd the driver checks if
the link_id indicated in the time event (and for which the cmd will be
sent) is valid and exists.
Clear the te_data::link_id when FW notifies that a session protection
ended, so the check will actually fail when it should.

As documented in the comment, this queue sync was here to
ensure that an async IWL_MVM_RXQ_NSSN_SYNC queue sync won't
race with setting up a new BA session with the same BAID.
However, we no longer do IWL_MVM_RXQ_NSSN_SYNC queue sync,
so we can remove this as well.
