Subject: [PATCH 3.10] iwlegacy: fix rate control regression
Date: Tue,  4 Jun 2013 14:19:10 +0200	[thread overview]
Message-ID: <1370348350-17193-1-git-send-email-sgruszka@redhat.com> (raw)

Since driver does not use control.rates[0].count, we have never set that
variable. But currently, after rate control API rewrite, this is required
by mac80211. Otherwise legacy rates control does not work and we transmit
always at 1Mbit/s on pre 11n networks.
