From 3394af677cadd1f9b877100312c830d87488fcfb Mon Sep 17 00:00:00 2001 From: Ansuel Smith Date: Wed, 2 Jun 2021 01:49:50 +0200 Subject: mac80211: split ath patch in dedicated subdir The ath patch number is already large and adding other patch for ath11k will add more confusion with the patch numbering. Since the support of ath11k based device is imminent, prepare the mac80211 ath patch dir and split it in the dedicated ath5k, ath9k, ath10k and ath11k (empty for now).
