At first glance it looks very reasonable to me.  I even agree with some
of the comments that suggest changes to the Open vSwitch netdev

I spotted at least one printf() that should be a VLOG_*() or removed.

I think there are a few opportunities for common code between the Linux
and FreeBSD implementations, but that can come later.

A comment mentions a need to edit coverage-counters.c but that should
not be necessary.  Just add COVERAGE_DEFINE(...name...); at the top

I look forward to a signed-off version.

I didn't try building it but I probably will (in a FreeBSD VM) before I
apply it.
