tcpdump and pcap on multiple interfaces

["lei wei" <weilei1983 () gmail com>]

Hello all,

I'm trying to capture packets from two network interfaces on FreeBSD using
pcap. From what I read about,
a "-i any" can be used on Linux to capture from all interfaces. But FreeBSD
doesnt seem to recognize it.
I wonder if there's a way to capture on multiple interfaces by something
like link aggregation
except launching several capturing processes and merge&sort?

Thank you.
