Subject: app/testpmd: fix latency stats deinit on signal
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8b36297d15f90265b50fae211157dff573513359;p=dpdk.git

app/testpmd: fix latency stats deinit on signal

On receiving signal, testpmd showing warning as
"LATENCY_STATS: failed to remove Rx/Tx callback"
because rte_latencystats_uninit is called without
checking if latencystats is enabled or not.

After this fix, rte_latencystats_uninit will be
called only if latencystats is enabled.
