Sure, which is why the second patch I posted has:
+int bpf_maxbufsize = (256 * 1024) /* XXX should be set dynamically */
I use grep a lot, so I was trying to fit the comment on the same line
as the variable. 256K is where I crossed over the point of
diminishing returns on a 133MHz Pentium (Intel Endeavour motherboard).
After sleeping on it, it should really be 1Mbyte or so for modern
machines with gigabit ethernet.
