poudriere testport log:

Though, I am annoyed that the log exposes internal information in the environment variable list at the start, like the *_PROXY variables. Is there an automatic way to strip those out?

Thanks for the update :)

MAX_NETMAP_OSVERSION=   1199999  # Doesn't build w/NETMAP on 12

@erj, is it still true?

I think so; IIRC it's because FreeBSD 12.0 is missing the driver-specific netmap headers (due to the in-kernel version of em having NETMAP integrated into iflib), and we don't include them in the OOT driver because we don't want to maintain them.

Committed, thanks!
