I'm not sure if it can be got from the market easily.

I would like to say, mt7668 is based on new MTK wifi architecture. as
for mt7662/mt7612/mt7610, they all belong to legacy Ralink based design.
of course, we will never see any new chip based on Ralink based design
wifi in the future.

There must be really lots of differences exist between two types of
devices, such as MCU firmware download, MCU control interface, tx/rx
path, even hardware register layout all changed and so on.

I guess the hardware abstraction layer needs to be largely adjusted to
add the new device mt7668u into mt76 driver. And even I think it would
be easier for development and maintenance if we make a separate driver
and then pick up some pure software components from mt76 to reuse.

Maybe it's the time I want to test your tree first with 7612u (?) or
mt7610u (?) , what is suggested? and see how big the gap between this
two type of devices and last write some code based on your tree to test
mt7668u
