FreeBSD VPP Port

Hi Folks,

Thanks to help from jrm@ since the end of last week VPP is now available as a FreeBSD port.

https://cgit.freebsd.org/ports/commit/?id=8ac9dd794c8fafcd763dc541c13790bcc23699b3

The port is based on VPP 2024.06 with some minor changes to enable DPDK on FreeBSD.

From a FreeBSD system installing VPP should now be as simple as running:

# pkg install vpp

There are still a few things we need before this is a complete port:

 - FreeBSD specific configuration documentation
 - Example config files
 - rc scripts to run vpp as a service

This is a great starting point for the community and are looking forward to users reporting their success running VPP on FreeBSD or any issues they encounter.

I look forward to your feedback.

Tom
