   3 Subject: [PATCH] ath10k: Fix failure to send NULL func frame for 10.4
   4
   5 This partially reverts 'commit 2cdce425aa33
   6 ("ath10k: Fix broken NULL func data frame status for 10.4")'
   7 Unfortunately this breaks sending NULL func and the existing
   8 issue of obtaining proper tx status for NULL function will be
   9 fixed. Also update the comments for feature flag added to be
  10 useless and not working
  11
  12 Fixes: 2cdce425aa33 "ath10k: Fix broken NULL func data frame status for
  13 10.4"
