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).

Subject: [PATCH] ath9k: force rx_clear when disabling rx
|
|
|
|
This makes stopping Rx more reliable and should reduce the frequency of
|
|
Rx related DMA stop warnings. Don't use rx_clear in TX99 mode.
