Subject: [PATCH v2 7/8] mac80211: add parse transmit power envelope element
Date: Fri, 20 Aug 2021 08:20:40 -0400 [thread overview]
Message-ID: <20210820122041.12157-8-wgong@codeaurora.org> (raw)
In-Reply-To: <20210820122041.12157-1-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.
