From 41fdf0974d9eb81215cb578211a6d8f8a022a9eb Mon Sep 17 00:00:00 2001 From: Nishant Sarmukadam Date: Fri, 12 Nov 2010 17:23:48 -0800 Subject: [PATCH] mwl8k: rf_tx_power cmd not supported by AP firmware APIv1 APIv1 AP firmware does not support the RF_TX_POWER command. It supports the similar TX_POWER command. Signed-off-by: Pradeep Nemavat Signed-off-by: Nishant Sarmukadam Signed-off-by: Brian Cavagnolo Signed-off-by: John W.
