From 1a8496137d3707061758df1f7df1e7700a4863fd Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Thu, 22 Sep 2011 15:14:52 -0700 Subject: [PATCH] iwlagn: update rate scaling with BA notifications In the current code, the rate scaling isn't fed with statistics from the BA notifications. This is since my patch: iwlagn: reclaim the packets in transport layer Fix that. Signed-off-by: Emmanuel Grumbach Signed-off-by: Wey-Yi Guy Signed-off-by: John W.
