The iBFT is Ethernet-centric in providing only six bytes for a MAC address. This is most probably an indirect consequence of a similar design flaw in the Windows NDIS stack. (The WinOF IPoIB stack performs all sorts of contortions in order to pretend to the NDIS layer that it is dealing with six-byte MAC addresses.) There is no sensible way in which to extend the iBFT without breaking compatibility with programs that expect to parse it. Add the notion of an "Ethernet-compatible" MAC address to our link layer abstraction, so that link layers can provide their own workarounds for this limitation.
