[dpdk-dev] [PATCH] i40e: fix packet stats getting

[Jingjing Wu <jingjing.wu@intel.com>]

The statistics queried by calling rte_eth_stats_get are zero when
the API is first called on the port. The root cause is because of
offset_loaded flag is not set correctly after device started.
This patch fixes this issue by resetting statistics at initialization
time, at the meanwhile the resetting process will set offset_loaded
flag.

Fixes: 4861cde46116 ("i40e: new poll mode driver")
