Subject: [RFC v2 3/6] mac80211: add hardware flags for TPC support
Date: Tue, 20 Sep 2022 12:40:29 +0200 [thread overview]
Message-ID: <20220920104032.496697-4-jelonek.jonas@gmail.com> (raw)
In-Reply-To: <20220920104032.496697-1-jelonek.jonas@gmail.com>
This patch adds two hardware flags for drivers to indicate their
transmit power control (TPC) capabilities: TPC per packet or TPC
per mrr stage of each data packet. The driver has to register with its
TPC capabilities when it is registering at the mac80211.
