LACP LAGG device problems

[Barney Cordoba]

I wasn't referring to science projects. Nor did I say it wasn't useful.
Only that 10g is cheap now and quite a bit better. LAGG isn't perfect.

Hah!

I'm pushing 20GE out using lagg right now (and fixing the er, amusing
behaviour of doing so.) I'm aiming to hit 40 once I get hardware that
doesn't get upset pushing that many bits. The netops people at ${JOB}
also point out that even today switches occasionally get confused and
"crash" a switchport. Ew.

So yes, there are people using lagg, both for failover and throughput reasons.

I'm working on debugging/statistics right now as part of general "why
are things behaving crappy" debugging. I'll see about improving some
of the peer reporting at the same time.
