From ccb6c1c0ec2b76a41c8c85747b1a671e71b97e64 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 28 Apr 2011 07:27:08 -0700 Subject: [PATCH] iwlagn: dont update bytecount table for command queue The device doesn't use the bytecount table for the command queue, only for aggregation queues to make aggregation decisions. So don't update it for the command queue (and we even updated it with wrong values).
