From ca48ebbc7ea7e82e3ae4b55aacead0cdb54ff008 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Mon, 15 Feb 2016 12:34:10 +0200 Subject: mac80211: remove ieee80211_get_key_tx_seq/ieee80211_set_key_tx_seq Since the PNs of all the tx keys are now tracked in the public part of the key struct (with atomic counter), we no longer need these functions. dvm and vt665{5,6} are currently the only users of these functions, so update them accordingly.
