This driver is quite nice mix of rt2800pci and Mediatek/Ralink driver,
where MT7xx code was copied into rt2x00 from venodr driver. It can be
good start for adding support for mt7xx devices to rt2x00.

Indeed, it is hard to find it.

Yep, some substantial amount of work is needed to add support to new
MT7xxx chips properly to rt2x00.
