This code snippet doing sanity check is copied from other functions defined in the same file 
lib/librte_ether/rte_ethdev.c, and there are plenty of legacy code in this file doing the similar
BSD style thing. I'd suggest somebody to clean all those kinds of BSD style code from DPDK code, 
in a separated patchset.
