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

["Ferriter, Cian" <cian.ferriter@intel.com>]

Passing a socket id of "rte_socket_id()" can cause problems in non DPDK applications as there is a dependency on the current logical core we are running on.
Passing " rte_lcore_to_socket_id(rte_get_master_lcore())" as the socket id to rte_memzone_reserve resolves these issues as the master lcore doesn't change.

Change the socket id that is passed to rte_memzone_reserve from the socket id of current logical core to the socket id of the master_lcore.
