This bug is not about TSO + PF, just about TSO, which seems to work fine now
(when not used in conjunction with PF).

PF is inserting bogus TCP checksums into TSO segments.  Some interfaces say
gee, some idiot didn't read the spec and ignore the checksums, while other
interfaces say hey, this is not a TSO packet and drop it.

The Xen network (at least as implemented in EC2) falls into the second
category.
