From d58c8f4029fa2c214454d7a5229e4964cbbc8fe1 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Fri, 26 Jan 2018 23:24:59 +0100 Subject: [PATCH] mac80211: revert "wireless: set correct mandatory rate flags" Revert upstream commit 1bd773c077de "wireless: set correct mandatory rate flags", as it breaks 11s interoperability: nodes can only associate when neither or both have this patch. As this is a regression from released versions, revert to the old code for now.
