I think it's better to think of it as a piece of hw (the nic)
trying to be managed by two different OSs: host and BMC.
it's surprising that it works at all, since there's no real
standard for sharing the hardware. I think all this adds up
to a good argument for non-shared nics. (that doesn't necessitate
a completely separate BMC-only fabric of switches, though.)
