OK, new patch at

http://andre.people.digirati.com.br/dragonfly/patches/tcpdrop/tcp_subr_shutdown.patch

This adds "net.inet.tcp.drop" and "net.inet.tcp.shutdown", and their v6
version.

Do you think sodisconnect() would be just as fine as soshutdown()? I'm
asking because, since sodisconnect() expects the same argument of
soabort(), I can pass a pointer to the respective function, which I think
it's neater. If sodisconnect() is fine, there's a patch that uses it
instead at

http://andre.people.digirati.com.br/dragonfly/patches/tcpdrop/tcp_subr_disconnect.patch

Anyway, I hope it's alright now :) If all is fine, I'll work on adding
command line options to tcpdrop(8) so that you can choose which sysctl
it'll  use.
