While this is currently the right thing to do, it might make more sense
to disable all this checksum verification stuff only for outgoing traffic.
Unfortunately our current captures don't support that distinction. What
would be required where to make this possible?
- Add a metadata element "direction" to the capture information provided
by the network driver and
- add "direction" element to libpcap packet header and fill it with the
information from above.
How much work would that amount to?

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
