Modify the pseudo-header checksum functions.
- Remove the initial checksum, which we don't use anywhere.
- Add the upper-layer protocol to the IPv6 function. Currently
this is always the same as the next header field in the IPv6
header, but technically it's the upper-layer header after all
the extension headers. This is required to support fragments.
