Support TSO over encapsulation (with GSO_PARTIAL), and over VLANs (which the code already handled but we didn't advertise). Also correct our handling of IPID mangling.
I couldn't find documentation of exactly what shaped SKBs we can get given, so patch #2 is slightly guesswork, but when I tested TSO over both underlay and (VxLAN) overlay, the checksums came out correctly, so at least in those cases the edits we're making must be the right ones. Similarly, I'm not 100% sure I've correctly understood how FIXEDID and MANGLEID are supposed to work in patch #3.
