From fac6b6a065da42f826088c58bddad82e1b1ccb40 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 23 Oct 2010 17:45:38 +0200 Subject: [PATCH] ath9k: resume aggregation immediately after a hardware reset Since aggregation is usually triggered by tx completion, a hardware reset (because of beacon stuck, tx hang or baseband hang) can significantly delay the transmission of the next AMPDU (until the next tx completion event). Fix this by rescheduling aggregation after such a reset. Signed-off-by: Felix Fietkau Cc: stable@kernel.org Signed-off-by: John W.
