Subject: [PATCH v4 6/6] mac80211: save transmit power envelope element and power constraint
Date: Fri, 24 Sep 2021 06:00:52 -0400	[thread overview]
Message-ID: <20210924100052.32029-7-wgong@codeaurora.org> (raw)
In-Reply-To: <20210924100052.32029-1-wgong@codeaurora.org>

This is to save the transmit power envelope element and power
constraint in struct ieee80211_bss_conf for 6 GHz. Lower driver
will use this info to calculate the power limit.
