[PATCH] USB: usbnet (5/9) module for genesys gl620a cables

Browse source 
This moves the GeneSys GL620USB-A support into its own driver file.
It also fixes a "return wrong skb" glitch in the rx unbatching, as
recently reported, and adds some missing byteswaps in the special
"genelink" headers (so it might now work on big-endian Linux).
