[dpdk-dev] [PATCH] testpmd: fix crash in txonly mode and when using tx_first

[David Marchand]

From: Adrien Mazarguil <adrien.mazarguil@6wind.com>

This crash was believed fixed by commit 5886ae07d211e4b5e49806dd183812beb31c67ad,
but the actual issue is that the core ID provided to rte_lcore_to_socket_id() is
wrong. It must be looked up in fwd_lcores_cpuids[].
