From 39df5e8233bf34696204207c7594a0a6320fa044 Mon Sep 17 00:00:00 2001 From: Zhaoyang Liu Date: Fri, 13 Mar 2015 17:37:55 +0530 Subject: [PATCH] mwifiex: get rid of BA setup helper functions This patch removes BA setup helper routines mwifiex_is_bastream_setup and mwifiex_is_amsdu_in_ampdu_allowed. Current code will use two functions to check bastream setup and amsdu in ampdu. This patch change these functions to flags, thus avoiding redundant spin_lock check while dequeuing TX packets.
