Subject: [PATCH 07/20] iwlwifi: nvm-parse: advertise IEEE80211_VHT_EXT_NSS_BW_CAPABLE in VHT
Date: Fri, 15 Feb 2019 13:49:11 +0200 [thread overview]
Message-ID: <20190215114924.2545-8-luca@coelho.fi> (raw)
In-Reply-To: <20190215114924.2545-1-luca@coelho.fi>
From: Johannes Berg <johannes.berg@intel.com>
We support this, so we should advertise it. In fact, if we don't,
mac80211 will do it for us (as we advertise SUPPORTS_VHT_EXT_NSS_BW
to it), but that requires a memory reallocation which is wasteful:
ieee80211 phy0: copying sband (band 1) due to VHT EXT NSS BW flag
Set the flag here to avoid that.
