ANALYSIS: most other xmit/frame generation flows:
- take next seqnum from pmlmeext->mgnt_seq
- call SetSeqNum to write it into the packet
- increment pmlmext->mgnt_seq
- and set it into pattrib->seqnum
Then in HAL, update_txdesc will either use hardware seq number if !pattrib_qos_en,
otherwise SET_TX_DESC_SEQ_8812 w/ pattrib->seqnum.
Also worth noting is prior update_monitor_frame_attrib/update_mgntframe_attrib call
merely set pattrib->seqnum to pmlmeext->mgnt_seq, but do NOT increment mgnt_seq.
Also they both set qos_en=_FALSE, which induce HW seq numbers.
The code below, however, appears to read the seq num out of the injected packet,
update the global pmlmeext->mgnt_seq with the injected seqnum, and then set
global pmlmeext to next seq. IMHO it appears to be doing the wrong thing, since
it is both updating pmlmeext from data in the packet, and all those values
are ignored because qos_en=_FALSE and thus HW seq is just used.
Ideally it would be nice to be able to control the sequence number, but the
strong coupling to qos_en makes that difficult right now. So we will just
use the default HW mode. However, we are going to skip some of the extraneous
steps this original code did by simply accepting:
- update_*_attrib called prior already set seqnum from pmlmeext
- so all we need to do is mgnt_seq++ just in case
- (and it seems we can avoid the SetSeqNum call)
