Actually, dladm has two separate notions of bge0 -- one at the device layer, and one at the link layer. After Clearview's Vanity Naming is introduced, the device layer (show-phys) will remain "bge0" but the link layer (show-link) will show whatever name the adminstrator has chosen, or bge0 by default. Note that if the administrator names an interface "maint0", then that means they will still have /dev/bge0, but will also have /dev/net/maint0 (/dev/net is where Clearview proposes to put the vanity names for network devices).
Seems reasonable.
That's one way to think about it -- but really, it represents whatever has been plumbed as an IP interface. Since the IP interface name is derived from the link-layer name (when one exists), aforementioned vanity naming will allow the administrator to have vanity names at this layer.
Ok.

Yeah. Now, I know this has /nothing/ to do with what's on Clearviews' table at the moment, but I wish the above weren't so. E.g. it leads chicken/egg problems with dynamic addressing (NWAM, assigning one interface based on the prefix of another (DHCPv6/IPv6 RA interaction)), doesn't it?

Isn't this ever so /slightly/ at odds with the previous? :) Anyway, not $SUBJECT - forgive me.
Well, you could view IPMP as a special-case today, as it fuses together one or more IP interfaces (but the representation will be changing as part of the Clearview IPMP Rearchitecture). I've got a document that describes all of this stuff in a bit more detail, but it's not yet ready for consumption.
