[dpdk-dev] [PATCH] lib/librte_ether: change socket_id passed to rte_memzone_reserve

You don't describe what is the problem. In another mail, you say
"The original suggestion also fixes the crash that I was seeing because
of memory being reserved from a numa node with no "--socket-mem" allocated."
Please describe it clearly in the commit log.

You should also explain what this rte_memzone_reserve() is for,
and what are the incidences of your changes.

Thanks
