mwifiex: AMPDU support for TDLS link
This patch adds AMPDU support for TDLS link. We have set 11n
capabilities including AMPDU parameters during ENABLE_LINK.
We set a variable in RA list to indicate this as TDLS link.
This patch uses these capabilities to know if AMPDU is allowed
on TDLS link and enables AMPDU aggregation for TX and RX reording
support for RA list for this peer.
