Mac80211 ath patch split proposal

[Ansuel Smith]

Hi,
since we are starting to add support for ath11k i was thinking... To
have things organized
and remove some confusion, I was thinking if it wouldn't be better to
split the ath
patch dir to 3 (or 4) sub directory and introduce patch for ath9k,
patch for ath10k
and patch for ath11k with a 4th optional dir that apply to ath general
directory?
What do you think about this change?
The mac80211 makefile already have a way to handle patch split in multiple dir
so adding extra dir is not really harmful.
