There are many possible values of ip_summed, why would you go to do_send if
for example it was set to CHECKSUM_COMPLETE?

I think you are just rushing this change, take your time and implement the
fix properly.

For example, if you only expect two possible values here (CHECKSUM_PARTIAL
and something else), design your test so that it only allows those two
values and therefore you'll be documenting this invariant.
