From a0f995a561d90636120bce2e89157b537a174c92 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Thu, 13 Mar 2014 14:30:47 +0200 Subject: mac80211: add status_driver_data array to ieee80211_tx_info Drivers might want to have private data in addition to all other ieee80211_tx_info.status fields. The current ieee80211_tx_info.rate_driver_data overlaps with some of the non-rate data (e.g. ampdu_ack_len), so it might not be good enough. Since we already know how much free bytes remained, simply use this size to define (void *) array. While on it, change ack_signal type from int to the more explicit s32 type.
