Even if a bridge is empty it seems impossible to add pppoe to it. This
doesn't change if the first bridge member has an MTU identical to that
of the pppoe interface (thank you to Martin Reindl for a patch
enabling mtu changes on Sun quad ethernet). For my own, and anyone
else's reference, the bridge's own MTU is hardcoded to ETHERMTU (1500).
Now, I can go through the source to if_bridge.c and find the
definitive answer, but I thought I'd ask here in case anyone had an
immediate answer, even if delving into the depths of OpenBSD is new
knowledge for me. The bridge and brconfig man pages aren't
illuminating in this regard.
Alternatively, it would be good to know if I'm doing something
foolish, if I find a way to get the source to accept pppoe interfaces
- could there be a hidden side effect?
To answer my own question. No, it's not possible as the source seems to
prohibit this.
It's trivial to change the source to force it to accept PPPoE
interfaces, and I now have a bridge with PPPoE on it. Unfortunately I'm
not sure if it's actually working as a bridge, which is a minor
disadvantage.. Hopefully it's easy to make this work
