Mt76 wireless driver debugging

I'm going to give the new build a while to cook before I cast any feedback one way or another.

In the meantime, I just noticed this:

Specifically:

Query the status of WED

To see which flows are actually getting off-loaded. This command works only for router mode (not AP):

# cat /sys/kernel/debug/mtk_ppe/bind
01dd0 BND IPv4 5T orig=xxx:11068-10.1.10.241:33328 new=xxx:11068-10.1.10.241:33328 eth=xx:xx:xx:xx:xx:xx-xx:xx:xx:xx:xx:xx etype=0008 vlan=0,129 ib1=21403a8d ib2=007e0060

The verbiage, "This command works only for router mode (not AP)", is new to me. Anyone know when this was added to the E8450 TOH page?
