Subject: app/testeventdev: launch order lcores
X-Git-Tag: spdx-start~2595
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=33b7483db1707e948afd545f16867ce0a867026e

app/testeventdev: launch order lcores

The event producer and master lcore's test end and
failure detection logic are common for the queue and
all types queue test.Move them as the common function.
