Subject: mac80211: Use only precedence level of DSCP field for frame classification
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2f58bbf27fe5321a7a208be9071efc54e8a8a3bd;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mac80211: Use only precedence level of DSCP field for frame classification

Bit 4-5 of DSCP should not be considered by classify_d1. The
802.11 QoS Priority field is only depending on the precedence level.
