From c3972591d991a82bad67522a60a3a0d8f7dceb56 Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Sat, 29 Apr 2017 13:03:42 +0100 Subject: [PATCH] staging: vt6656: vnt_update_ifs set max_min based on short slot time. 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.
