Just to the names.  Its name exposes the implementation details.  I'd 
prefer net.inet.ip.maxqlen, net.inet.ip.qdrops, and net.inet.ip.qlen.

BTW, I would also support changing the default queue len to some larger 
number.

Also, the qdrops is available via netstat, right?  Why expose it here, 
too?
