Subject: [PATCH] QCA9984 VHT160 support
Date: Fri, 16 Sep 2016 09:51:31 +0200 [thread overview]
Message-ID: <5c915231-db74-a147-f904-21c09d8a1ff0@dd-wrt.com> (raw)
In-Reply-To: <8737l2ee1y.fsf@kamboji.qca.qualcomm.com>
[-- Attachment #1: Type: text/plain, Size: 234 bytes --]
This patch adds full VHT160 support for QCA9984 chipsets
Tested on Netgear R7800. 80+80 is possible, but disabled so far since it
seems to contain glitches like missing vht station flags (this may be
firmware or mac80211 related)
