From de40f316c01b1ba9535e6dc99f6a67e7655b07da Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 20 Oct 2010 03:08:53 +0200 Subject: [PATCH] ath9k_hw: extend ath9k_hw_set_txpowerlimit to test channel txpower ath9k_hw_set_txpowerlimit gets an extra boolean parameter that - if set - causes the rate txpower table and the regulatory limit to be calculated and stored, without changing hardware registers.
