Firstly, I don't see why changing the filtering rules currently in
use should require you to reload the entire ruleset. To change a
single rule then requires you to `disconnect' from the network
(ifconfig down), remove the BPF rules, load a new set, and ifconfig
Those two statements are unrelated. The ability to install a new
filter program is quite distinct from the actual mechanics of
uploading the program to the kernel. I don't see why it should ever
be necessary to turn the network interface off.
