I sent this driver when mainlining the support for EdgeRouter Lite
(http://www.ubnt.com/edgemax), and at the time I thought it was purely
Octeon specific HCD driver (the source code does not give much hits
about the actual HW block, and the vendor's GPL tar ball is my only
documentation). On that hardware it works well - I have run stress tests
with duration of couple of days with the mainline kernel and never
seen any stability or any other issues. But if you consider it as a
general purpose DWC2 driver it's probably a pile of crap, as it's full
Octeon-specific hacks and assumptions.
