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