[][MAC80211][hnat][Fix eth0 transition timed out happened in 1_WAN, 3_LAN bi-direction test load unbalance scenario]

[Description]
Fix eth0 transition timed out happened in 1_WAN, 3_LAN bi-direction test
load unbalance scenario.

This patch setup QDMA queue 6~11 when pppq is enabled, where queue 6~11
are used to transmit short packet in PPPQ mode,
set the min rate to 1Mbps to avoid the priority of QDMA queue is
unlimited and blocked the CPU packet transmission.

Without this patch, the 1_WAN, 3_LAN bi-direction load unbalance test
would trigger eth0 QDMA transmission timeout in mt7981(Cheetah).
