From 09869495616af7e5098aabb6f3eefdf885235699 Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Wed, 21 May 2014 22:02:31 -0700 Subject: [PATCH] mwifiex: update seq number correctly for packets from TDLS peer This patch adds handling of updating rx sequence number for packets received from TDLS peer. Current implementation of mwifiex_queueing_ra_based assumes station would always receive packets from AP which is not true in case of TDLS. Fix this by adding this case.
