Add support for Infiniband network interfaces (IPoIB).
OpenStack ironic references Infiniband interfaces via a 6 byte 'MAC address' formed from bytes 13-15 and 18-20 of interface's hardware address. This address is used as the ethernet_mac_address of Infiniband links in network_data.json in configdrives generated by OpenStack nova. We can use this address to map links in network_data.json to their corresponding interface names. When generating interface configuration files, we need to use the interface's full hardware address as the HWADDR, rather than the 6 byte MAC address provided by network_data.json. This change allows IB interfaces to be referenced in this dual mode - by MAC address and hardware address, depending on the context. Support TYPE=InfiniBand for sysconfig configuration of IB interfaces.
