From d1a566bec5887988cd7e4b7cf98b05e1ff7a0f8a Mon Sep 17 00:00:00 2001 From: Erik Stromdahl Date: Mon, 18 Jun 2018 17:01:21 +0300 Subject: ath10k: fix bug in masking of TID value Although the TID mask is 0xf, the modulus operation does still not produce identical results as the bitwise and operator. If the TID is 15, the modulus operation will "convert" it to 0, whereas the bitwise and will keep it as 15. This was found during code review.
