Date: Sat, 29 Apr 2017 13:03:42 +0100 Message-Id: <20170429120345.3782-1-tvboxspy@gmail.com> (sfid-20170429_140415_688488_C1C5B5C1) Sender: linux-wireless-owner@vger.kernel.org List-ID: Short slot time is controlled by mac80211 so there is no need to find odfm rates. Merge PK_TYPE_11B and PK_TYPE_11GA & PK_TYPE_11GB into one else and switch on short slot time.
