Thank you. I applied this to master, adding the following NEWS entry:
- FreeBSD is now a supported platform, thanks to code contributions from
Gaetano Catalli, Ed Maste, and Giuseppe Lettieri.

Yes, I just wanted to offer this part up for comment first (and also
because git-format-patch shows it as a delete and add so the changes
themselves are not as obvious).

Yes, this appears to be an oversight. 1518 is probably reasonable.

Thanks Ben,
all of your comments look sensible and useful to me. I add some reply below.

Hi,
here is a new version of the FreeBSD porting patch, signed-off by Catalli.
W.r.t. the previous patch, I only replaced a printf with a VLOG_WARN_RL
and declared a COVERAGE counter (as suggest by Ben below), and removed
some trailing white space to make git-apply happy.
Regards,
Giuseppe

Hi,
the attached patch implements new netdev classes for "system" and "tap"
devices in FreeBSD, by using the libpcap library. With this patch (and
some firewall rules) the user-level datapath of Open vSwitch can be made
to work on FreeBSD.
