What are people's thoughts on extending ifconfig(8) to configure
netgraph-based interfaces, such as ng_fec(4)? The recent trend has
been to allow all kinds of different network interfaces to be
configured uniformly through ifconfig. Is there any reason
functionality based on netgraph nodes should be excluded?

On a related note, is there any reason to not to use netgraph to
implement things like FEC for production use? Are there any advantages
to using a normal pseudo device (like NetBSD's agr(4)) instead of
improving the netgraph node? Performance concerns, anything like that?

Any input on either issue would be appreciated.

Dima.
