Errors on running kipfw with vale switches

[h bagade]

Hi all,

I want to run userland ipfw with netmap support(kipfw). When I try to
follow the example to test kipfw, it encounters an error on following
command:

# connect the firewall to two vale switches
./kipfw valeA:f valeB:f &

command output:
root at zharf-bsd-9:/ipfw-user # ./kipfw valeA:f valeB:f &

I am running firewall on FreeBSD 9.2-stable.
It seems that there is some problem with vale but I don't know what it
is! Is it possible that my netmap module doesn't support vale?
