Hi Peter,

It's as I suspected:

> [               0h] = reserved[ 4b]

This says there are 4 cipher suites to read.

This shows which ones are supported, and it properly shows 4 of them.

This is supposed to tell us what the maximum privilege level for those 4
cipher suites are, but the command only returns 2.  Uh oh ...

I'll need to think about how to work around this.  Maybe if this
happens, I could have bmc-config output "Unknown" or something, and it's
up to the user to force the configuration of something.  Let me think
about this and get back to you with a patch ...
