This is something added to FreeBSD after our snapshot. The Cadence net 
driver for the Zynq has similar code which Sebastian has amended. Check 
in sys/dev/cadence/if_cgem.c.

It might pay for us to add these to an RTEMS header to make porting simpler.

Please make sure your libbsd is up to date. I added support for device 
sysctl's on the master branch yesterday so that code should work.
