True, but you can't send a broadcast GetChAuthCap and just gather all the
answers like you can do with RMCP ping.

`idiscover` is much easier and faster to use than `idiscover -g -b 172.16.1.1 -e
172.16.1.254`. The latter takes like 15 minutes to complete versus like 2
seconds for plain `idiscover`.

Do you think implementing RMCP ping support in OpenBMC is feasible?
