From a4bcaf5556da649f0160e60fa7b4bb2c29801c12 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Thu, 4 Sep 2014 23:57:41 +0200 Subject: mac80211: extend set_coverage_class signature Extend mac80211 set_coverage_class API in order to enable ACK timeout estimation algorithm (dynack) passing coverage class equals to -1 to lower drivers. Synchronize set_coverage_class routine signature with mac80211 function pointer for p54, ath9k, ath9k_htc and ath5k drivers.
