New element: SetTCPChecksumIP6 - Calculates TCP/IPv6 checksum and sets the TCP header field.

[kkovacs]

The existing SetTCPChecksum element only supports TCP over IPv4. This is a new element that does the same for TCP over IPv6.

The new element's naming convention follows FastUDPSource and FastUDPSourceIP6, and is also the reason I've put this in tcpudp/ instead of ip6/.

The code is based mostly on the original SetTCPChecksum and the way FastUDPSourceIP6 calculates checksum for its packets.

I do see that a "CodeQL" build step is failing on the PR (but all builds are successful), but this one does not seem related to my code, it says:

"Semmle autobuild: no supported build system detected. We were unable to automatically build your code. Please replace the call to the autobuild action with your custom build steps."

Thank you very much! Could you just set the copyright correctly?

[tbarbette]

Can you add your name and copyright institution? Maybe add "based on settcpchecksum.{cc,hh}"

[kkovacs]

Yes, of course. I didn't want to claim too much credit, but the way you suggest it is a good way, referencing the others. Pushed!

[tbarbette]

Yes the codeql seemed to be a false positive, I'll check after it re-ran.

[kkovacs]

Copyright was changed as asked (thanks!), now I think only CodeQL is acting up again.

[tbarbette]

I found the problem, codeql does not compile with --enable-ip6 and therefore the element is missing a symbol. It's actually legit Should be fixed with the last commit. I'll merge when it passes. Thanks!

Bad luck... Github has an issue with name resolution right now and cannot resolve fast.dpdk.org... Will re-launch the CI in a bit.

Thanks for the quick merge, Tom! And thank you for doing fastclick!
