Hi,

I am trying to play with latency statistics library (a wrapper around
rte_metrics lib). Whenever I try to retrieve values using
rte_latencystats_get(), all the stats are 0.
Even after rte_latencystats_update() still no effect on the stats.

Does this library need NIC driver support?
Any help would be appreciated.

Testing on l2fwd example app using:
-- DPDK 18.11
-- Mellanox ConenctX-5 EN 100G
-- Ubuntu 18.04
-- fw 16.24.1000

Thanks,
Arvind
