mwifiex: fix WPS eapol handshake failure
commit f03ba7e9a24e5e9efaad56bd1713b994ea556b16 upstream.
After association, STA will go through eapol handshake with WPS
enabled AP. It's observed that WPS handshake fails with some 11n
AP. The reason for the failure is that the eapol packet is sent
via 11n frame aggregation.
The eapol packet should be sent directly without 11n aggregation.
This patch fixes the problem by adding WPS session control while
dequeuing Tx packets for transmission.

mwifiex: fix 11n rx packet drop issue
commit 925839243dc9aa4ef25305f5afd10ed18258a4ac upstream.
Currently we check the sequence number of last packet received
against start_win. If a sequence hole is detected, start_win is
updated to next sequence number.
Since the rx sequence number is initialized to 0, a corner case
exists when BA setup happens immediately after association. As
0 is a valid sequence number, start_win gets increased to 1
incorrectly. This causes the first packet with sequence number 0
being dropped.
Initialize rx sequence number as 0xffff and skip adjusting
start_win if the sequence number remains 0xffff. The sequence
number will be updated once the first packet is received.

Current implementation, for retrieving priv from adapter,

different types, bss_index may not be unique.
Use bss_type along with bss_num to retrieve the priv.
bss_index is removed with this change.

mwifiex: correct AMSDU aggregation check
The commit "mwifiex: remove list traversal.."(fcf2176c87..)
wrongly modifies AMSDU aggregation check. Due to this even though
packet size for iperf traffic is already large, we unnecessarily
try to aggregate them which adds some delay. If Tx iperf is started
on UUT for 30 seconds, UUT keeps sending Tx packets for few more
seconds.
That commit is reverted to fix the problem.
Also, MIN_NUM_AMSDU check is moved inside the loop to optimize the
loop.

mwifiex: put multicast/broadcast packets to the same RA
For ad-hoc mode, RA is created for each peer connected. In case of
multicast traffic new RA will be created for each multicast
address. While processing Tx packets we have to go through this
RA list. We can avoid some RA nodes by sharing same RA for both
multicast and broadcast packets.
Therefore "memset(0xff)" is used to treat multicast packet as broadcast
one while choosing RA.

mwifiex: remove list traversal in mwifiex_num_pkts_in_txq
Instead of counting the number of packets in txq
for particular RA list before AMSDU creation,
maintain a counter which will keep track of the
same.
This will reduce some MIPS while generating AMSDU
traffic as we only have to check the counter instead
of traversing through skb list.
