From eac4322729aebf01ae231d3b3f63aae73d469a57 Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Fri, 7 Feb 2014 16:27:28 -0800 Subject: [PATCH] mwifiex: handle AMPDU supported check for AP interface This patch fixes a bug where we were checking for AP's AMPDU param setting even when transmitting traffic to associated station. Patch adds provision to pass additional parameter ra_list pointer to function which checks if AMPDU is allowed. If current BSS type is AP, we check station's AMPDU params else we check AP's AMPDU params. Signed-off-by: Avinash Patil Signed-off-by: Bing Zhao Signed-off-by: John W.
