That little weird thing called binary compatibility. It is possible to
support IFF_PROMISC until the end of time, because the NIC promisc bit
is similarly binary. The change I propose is to regain what we have
(note: we "lost" this 5 years ago, and nobody has cared all
this time, keep that in mind :-)
How do we handle SIOCSIFFLAGS then?
Do we just cancel out all the counts if we are asked to clear the
IFF_PROMISC bit? That is definitely wrong, it blows away the entire
intention of having a count in the first place. Or do we make it act
as a "decrement 1 count"? That sounds equally lousy to me.
We can't just ignore the request by your very arguments. Right?
