From 7b05b0ab89e692eb45b011169afb2359d5d92c6c Mon Sep 17 00:00:00 2001 From: Vladimir Kondratiev Date: Thu, 27 Feb 2014 16:20:47 +0200 Subject: [PATCH] wil6210: fix BACK status processing When FW notifies about BACK status change, it provides ring ID. Process BA status for requested connection only. As for now, FW don't report Rx BACK status, it reports Tx one instead. As per current algorithm used in the firmware, imply Rx BACK state is in sync with Tx one Signed-off-by: Vladimir Kondratiev Signed-off-by: John W.
