From c7d9ed9ec9b2947a9c5dc5e2c7afce1fd3ad82cc Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Mon, 22 Jul 2013 19:17:40 -0700 Subject: [PATCH] mwifiex: maintain outstanding packet count for RA list instead of packet size Maintain total outstanding packet count for RA list instead of total outstanding size as packet count metric seems more reasonable for checking threshold etc. Signed-off-by: Avinash Patil Signed-off-by: Bing Zhao Signed-off-by: John W.
