Subject: [RFC 3/4] mac80211: add hardware flags for TPC support
Date:   Mon, 29 Aug 2022 16:41:46 +0200

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.
