Feature not implemented. We need SIOCGIFHWADDR for this, which is trivial to add, just takes someone to start... Well, actually the feature is implemented, but over the non-RT configuration interface /dev/rtnet: IOC_RT_IFINFO (see also rtifconfig tool). You may use this interface as is, but I would try to keep away from it with application code. Reason: The plans for the future are to kill /dev/rtnet and switch to IOCTLs (standard ones like above + our owns) over RTnet sockets also for configuration purposes. We now have mature user-space real-time and don't need such side channels anymore. The CAN stack in Xenomai already demonstrates this path nicely, and RTnet may even share device management code with the CAN stack one day.
