From 9e09fbc5e90247fc6e77fb6ba72dcbf8088cf59a Mon Sep 17 00:00:00 2001 From: Po-Hao Huang Date: Fri, 16 Jun 2023 20:55:37 +0800 Subject: [PATCH] wifi: rtw88: Skip high queue in hci_flush The flush period may not always intersect with DTIM and when that happens, an error log "timed out to flush pci TX ring[6]" is shown. Bypass this since hardware will do proper transmission on the next DTIM period for broadcast/multicast packets in high queue.
