Netmap on em(4) newcomer (first steps)

[Eduardo Meyer]

Hello,

I would like tro try netmap on em(4) device. Other than comping my kernel
with netmap what else I need to setup a "production-like" environment to
test it?

The scenario is a simple BGP router w/ FreeBSD forwarding packets from em0
to em1 with no NAT, etc.

I read something about using a special virtual switch (VALE), is it needed?
Or is it for testing scenarios only?

I want to try it on 9-STABLE.

Thanks!
