Log:
Ignore any IFF_MULTICAST flag specification in ioctl(TUNSIFMODE)
The previous commit resulted in the IFF_MULTICAST bit being lost
by existing programs usage of TUNSIFMODE - specifically, -stable's
ppp doesn't yet know that it needs to pass the flag in.
As NetBSD-current, OpenBSD-current and FreeBSD-current all expect
IFF_MULTICAST for this ioctl(), ignoring it in -stable is probably
the best compromise.
