It's outside of anything on Samba configuration to do what you want, but
another way to use both interfaces to their fullest, would be to "bond"
the two ethernet interfaces.  Your network switches would have to
support this and be configured, but then your two seperate 100MB/s
interfaces would be one single 200MB/s connection from your server to
your network with a single "logical" interface,  associated ip address,
and netbios name for it.
