fprobe on multiple ethernet interfaces

[User Ernie]

I am trying to use fprobe to capture netflow data on multiple ethernet
interfaces at once, the man page says you use the keyword 'any' as the interface
name, when I do that I get the following error in the logs and fprobe wont
start:

 fprobe[66637]: [CRIT]: pcap_open_live(): BIOCSETIF: any: Device not configured

it works fine with just a single ethernet interface specified.

Is the fprobe 1.1 port broken on FreeBSD or am I doing something wrong?
