Subject: [PATCH 10/31] mac80211: add to bss_conf if broadcast TWT is supported
Date: Fri, 18 Jun 2021 13:41:35 +0300	[thread overview]
Message-ID: <iwlwifi.20210618133832.f7c105237541.I50b302044e2b35e5ed4d3fb8bc7bd3d8bb89b1e1@changeid> (raw)
In-Reply-To: <20210618104156.747775-1-luca@coelho.fi>

From: Shaul Triebitz <shaul.triebitz@intel.com>

Add to struct ieee80211_bss_conf a twt_broadcast field.
Set it to true if both STA and AP support broadcast TWT.
