Hi all,

I'm working on FreeBSD-based configuration code dating back more
than 5 years.  Although this code uses NETGRAPH compiled into the
kernel, it also makes use of NGM_ETHER_DETACH and a self-rolled
NGM_ETHER_ATTACH to avoid having netgraph-attached interfaces when
mpd isn't needed.

In 2016, how is the state of ng_ether(4) performance to assert
whether this approach is actually useful or not.

Seeing that NGM_ETHER_ATTACH is not available and should usefulness
be implicated, would code for NGM_ETHER_ATTACH be merged into
FreeBSD?


Thanks,
Franco
