similar to: [PATCH v8 15/50] virtio_net: v1.0 endianness

Based on patches by Rusty Russell, Cornelia Huck. Note: more code changes are needed for 1.0 support (due to different header size). So we don't advertize support for 1.0 yet.

Feedback welcome, as always! (There's been talk of a virtualization git tree, in which case there'll be a decent home for these patches soon). Cheers, Rusty. == Add feature and GSO support to virtio net driver. If you don't do GSO, you can simply ignore the first sg element of every outgoing packet, and tack a dummy one on every incoming.
