I am not the DHCP package maintainer. :-)

I'm up to my earfulls already dealing with people trying
to slug broken patches into the kernel networking that paper
around application bugs. ;)

Unfortunately it looks like a properly formed sockaddr_ll,
the ifindex is in fact zero, so there is nothing we can do
to warn about this case.

The sockaddr_ll sits after the first sockaddr string in the ifreq, and
the rest remains initialized to zeros, thus the bind() succeeds.
