From e03bbb62cfdf539ae8110b297493c685f9d12774 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Sun, 13 Apr 2014 10:49:16 +0300 Subject: iwlwifi: don't disable SCD chain extension on newer devices 7000 device series have a fix for this hardware feature. Stop disabling it, and get an improvement in Tx throughput. This feature allows the scheduler to fetch more frames on the fly while an A-MPDU is being built - which means that we can get larger A-MPDU. This, of course, give an improvement in the Tx throughput.
