I think it may be possible to even support a few more things here.
According to the datasheet here:
http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/xl710-10-40-controller-datasheet.pdf
This can actually support 64 bytes beyond the tunnel header, which
would make for a total of 80 bytes. It looks like it can also support
IPv4 or IPv6 beyond just Ethernet as the encapsulated protocol.
Intel guys, can you confirm that this is correct?
