qcacld-3.0: disable pn check for ibss network, in security mode
qcacld-2.0 to qcacld-3.0 propagation
Multicast packets using different sequence number space
gets dropped on the host due to the existing logic of
running duplicate detection check and out-of-order packet check
on all non-aggregation (legacy) TIDs, since f/w uses a
special (non-aggregation) TID (18) to indicate these packets
to the host, irrespective of sequence number space.
The fix is in 2 parts:
1) Do only duplicate detection on mcast packets & not out-of-order check
(Also do dup-detection only if retry bit is set)
2) Instead of using mcast TID indicated by f/w, use the actual
packet TID from the Rx descriptor to perform the duplicate detection
and use a separate (new) field in rx_reorder_array to store
the last successful mcast sequence number. On the next mcast packet
perform the duplicate detection against mcast sequence number, rather
than the ucast sequence number.
