This has come up previously--right now, BPF will notify the user process
of an interface disappearing via ENODEV on any future operation on the
file descriptor. However, the version of DHCP we currently bundle does
not support this, and instead spins on the ENODEV rather than exiting.
David O'brien indicated that this improvement should come from the ISC
side and be imported, rather than bumping our dhclient off the vendor
branch. I believe Ted Lemon indicated that such a change would go into
version 3 of their DHCP client.
