Brooks Davis f2c99d387c 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.
