Not at present. There's an ioctl needed to enable immediate mode on
BPF,
On a hopefully final note,
It came back quickly when I passed a 1 in as the to_ms parameter, but is there
something I can define so that when it picks a packet off the wire, it reads it
_immediately_. The project I'm doing needs as little latency as possible in
picking up the frame. Thanks,

I had changed it to 0 last night, because the program would not run
if to_ms was -1. I'm about to go home and check what happens if I
change it to a 1.

Yes, there's nothing special about a value of -1 for the timeout; the
timeout value is, on systems using BPF (such as BSDs), just converted to
seconds and microseconds and passed to the BPF devi
