From dd5b6d0a2059027366028630746d951b1e1e24b3 Mon Sep 17 00:00:00 2001 From: Wey-Yi Guy Date: Thu, 25 Aug 2011 23:10:55 -0700 Subject: [PATCH] iwlagn: enable 11n aggregation without checking traffic load Enable HT aggregation when it reach reasonable traffic without checking traffic load which delay enabling the aggregation and lower the throughput but this behavior can be overwrite by module parameter this address https://bugzilla.kernel.org/show_bug.cgi?id=40042 Signed-off-by: Wey-Yi Guy Signed-off-by: John W.
