Module Name:    src

Modified Files:
        src/sys/netinet6: in6.c

Log Message:
This is ugly, but it is the simplest fix to avoid calling in the default
case:

    <driver>_ioctl(ifp, SIOCSIFADDR, struct ifreq *)

where it should be calling:

    <driver>_ioctl(ifp, SIOCSIFADDR, struct ifaddr *)

and "Bad Things Happen (TM)"

Returning an error is good enough because none of the drivers handle INET6.

The problem here is that handling SIOCSIFADDR is a kludge. The ioctl gets
passed a struct ifreq * from userland, but then in the control routines
SIOCSIFADDR is handled "specially", and we call:

        ifp->if_ioctl(ifp, SIOCSIFADDR, struct ifaddr *)

directly with the ifaddr we computed for that interface. It would be nice
if we called the ioctl routine if the original struct ifreq, and computed
the ifaddr, or passed it directly. This way all the ioctls would be treated
the same way, and we would not have the problem of pointer overloading.
