From 70418790437753faa9a6d7d5c567820e47838e85 Mon Sep 17 00:00:00 2001 From: Glen Lee Date: Thu, 4 Feb 2016 18:15:27 +0900 Subject: [PATCH] staging: wilc1000: add ops tx power in cfg80211 This patch implements set_tx_power and get_tx_power of cfg80211_ops. In addition, Id of HOST_IF_MSG_DEL_ALL_RX_BA_SESSIONS is changed with 37.
