As for checking against the normal MTU, does tcpdump/libpcap have

Only to the extent that it could infer that from the link-layer type.
(Jumbo frames might make that tricky.)
And since TSO _really_ works on the MSS of the *connection* not the MTU
of the link, knowing the link MTU doesn't really tell you much anyway.
I think the aforesuggested addition of the "is the checksum 0" would be
a sufficient addition to the existing heuristic.
