Multiple libpcap Ring Buffers?

Hey Everyone,

Quick question...

If I have an application that opens two packet captures sessions (ie eth0 and
eth1) does libpcap create two ring buffers?

Also if I set PCAP_FRAMES=max how much memory is that going to take?  I have
read some conflicting numbers.  I have seen ~50MB to ~130MB.

Thanks for all your help

Cheers

J.O.
