Yes, it will. There is a linux-firmware-wimax tree I'll ask David to pull
from.

Actually some of them could. I'll see to put them.

The reset ones I want to keep in there, as for support they come in 
very handy.

Very driver specific. These statistics refer to the way the device sends
and receives stuff, which is coalesced (so one of this packets doesn't map
to an IP packet).

This one belongs to debugfs.
