From ba905bf432f662cb907fd692a4f160e612c0408b Mon Sep 17 00:00:00 2001 From: Ashok Raj Nagarajan Date: Fri, 29 Mar 2019 16:19:09 +0530 Subject: mac80211: store tx power value from user to station This patch introduce a new driver callback drv_sta_set_txpwr. This API will copy the transmit power value passed from user space and call the driver callback to set the tx power for the station.
