Someone reported a problem with skge hardware receive checksumming and PPPOE

bytes the hardware computed checksum will be wrong.  

Not sure if this is correct, but shouldn't pppoe be doing the following:

Changing or expanding the link level headers should only mess
up the hw checksum if you are using CHECKSUM_HW, is that what
your skge driver is using?
