From 32a2be499c01ee523b28018d451b39ded4297b11 Mon Sep 17 00:00:00 2001 From: Miles Hu Date: Fri, 8 May 2020 05:54:57 +0300 Subject: ath11k: remove stale monitor status descriptor The driver is not handling monitor status descriptor whenever the done bit of status descriptor is not set by hardware. This leave a stale entry in monitor status ring and flooding warning message. Fix that by removing the descriptor and move forward to next one in monitor status ring.
