f1c6fc5f44 Remove dead code in dhclient(8)
The offending code has been dead ever since the import from OpenBSD in
r195805.  OpenBSD later deleted that entire function.

ba54a678f6 Allocate a struct ifreq rather than using a (wrong) computed size for
the BIOCSETIF ioctl.

The kernel always copies an entire struct ifreq and IPv4 addresses will
always fit in an ifreq.

On systems with pointers larger than 64-bits, the computed size will be
less than the size of struct ifreq, potentially resulting in the kernel
attempting to copyin memory from outside the allocation.

413d779950 dhclient: add support for interface-mtu (26)
Make dhclient set interface MTU if it was provided.

This version implements MTU setting in dhclient itself before it runs
dhclient-script.

681dc8671b Fix the logic to count the number of "live interfaces". With this change
dhclient now terminates when the underlying ifnet is destroyed (e.g.
on card eject).
