From ae172f61ff5d599fe56d2eec814e8310fda7cd43 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 6 Dec 2012 18:40:11 +0100 Subject: Revert "ath9k_hw: Update AR9003 high_power tx gain table" commit 9c170e068636deb3e3f96114034bb711675f0faa upstream. This reverts commit f74b9d365ddd33a375802b064f96a5d0e99af7c0. Turns out reverting commit a240dc7b3c7463bd60cf0a9b2a90f52f78aae0fd "ath9k_hw: Updated AR9003 tx gain table for 5GHz" was not enough to bring the tx power back to normal levels on devices like the Buffalo WZR-HP-G450H, this one needs to be reverted as well. This revert improves tx power by ~10 db on that device Signed-off-by: Felix Fietkau Cc: rmanohar@qca.qualcomm.com Signed-off-by: John W.

SKBs that are allocated in the HTC layer do not have callbacks registered and hence ended up not being freed, Fix this by freeing them properly in the TX completion routine.

If getting a new beacon from mac80211 fails, bf->bf_mpdu is not reset, yet the skb is freed, leading to a double-free on the next beacon tx attempt, resulting in a system crash.
