Subject: [PATCH v3 7/9] mac80211: add parse transmit power envelope element
Date: Fri, 3 Sep 2021 07:48:19 -0400 [thread overview]
Message-ID: <20210903114821.23346-8-wgong@codeaurora.org> (raw)
In-Reply-To: <20210903114821.23346-1-wgong@codeaurora.org>
The transmit power envelope elements in beacon is used to calculate
the power limit by lower driver, and sometimes it has more than
one elements in a beacon frame.
This is to add parse the transmit power envelope elements, then it
will be saved and transfer to lower driver to calculate the power
limit.
