Hello,

I'm looking at the mt7620 Ethernet driver and I see a lot of magic
happening for which I cannot find documentation anywhere.  Can anybody
tell me where I can get the datasheets / programmer's guide that
document these registers please?

Examples:
I/O to 0x7830, 0x7a40 -- Entries in the WAPI table?  That seems strange.

_mt7620_mii_write(gsw, gsw->ephy_base + 1, 22, 0x10cf);  The mt7620
programming guide only documents 0-6, while the 802.3-2005 has
everything from 16-31 marked as "vendor specific".  Also, what does port
31 do?
