Hi folks.

I don't see a generic infiniband discussion list anywhere, so I figured
I'd try a Linux infiniband list.

Does anyone know for sure if MAC addresses are unique in infiniband
networks, with or without ipoib?

sticking to IPoIB, please take a look at section 9.1.1. "Link-Layer Address/Hardware Address" of RFC 4391, and elsewhere in this doc to get answers to your questions below.

Or.

I know with ethernet, they're supposed to be, but:
1) Sun sometimes likes to put the same MAC address on more than one subnet
iun machines with more than one NIC
2) Some ethernet drivers let people change the MAC address

Is it about the same with infiniband?
