From c8442118ad9cd05cfe3b993f058e70ab25b1009a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 24 Oct 2012 10:17:18 +0200 Subject: cfg80211: allow per interface TX power setting The TX power setting is currently per wiphy (hardware device) but with multi-channel capabilities that doesn't make much sense any more. Allow drivers (and mac80211) to advertise support for per-interface TX power configuration. When the TX power is configured for the wiphy, the wdev will be NULL and the driver can still handle that, but when a wdev is given the TX power can be set only for that wdev now.
