Hi List!
Unlike rtm_msghdr, ifam_msghdr has no idea of the identity of the
process who
added or deleted an address.
This is important for processes which add/delete addresses while
listening for
3rd parties to add/delete addresses as well, so self generated
messages can be
ignored.
Here is a simple patch which adds ifam_pid to ifa_msghdr so the
identity of
the sender is known.

Unless anyone objects, I will add this soon.
If only it was that simple... See sys/compat/net/if.h how to do it
properly.
OK, I have a new patch for this here:
http://www.netbsd.org/~roy/ifam_pid_addrflags.patch
I took the liberty of adding ifam_addrflags while here, so that it can
be added to getifaddrs(3) and both save an extra ioctl per address for
programs like dhcpcd, which also decreases it's binary size.

Comments welcome.
