Subject: [PATCH v2 0/3] mac80211: Enable VHT for non chanctxes drivers

Fengguang's build with v1 yields kernel-doc warnings.
This v2 replaces the @channel+@channel_type kernel-doc entries in
struct ieee80211_conf with an @chandef.

Just saw you had already fixed that in your wip branch, thanks.

Subject: [PATCH v2 3/3] mac80211_hwsim: advertise VHT support also when channels == 1

From: Karl Beldan <[email protected]>

Drivers can now advertise VHT support even if they don't use channel
contexts.

Subject: [PATCH v2 1/3] mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chan

From: Karl Beldan <[email protected]>

Drivers that don't use chanctxes cannot perform VHT association because
they still use a "backward compatibility" pair of {ieee80211_channel,
nl80211_channel_type} in ieee80211_conf and ieee80211_local.
