[dpdk-dev] [PATCH 2/7] net/hns3: fix xstats statistics with id

[Lijun Ou <oulijun@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

Number of xstats item in rte_eth_xstats_get_by_id is obtained
by the eth_dev_get_xstats_count API, and the xstats_get_by_id
ops of the driver only needs to report the corresponding stats
item result.
However, a redundant code for reporting the number of stats items
in the hns3_dev_xstats_get_by_id API causes a problem. Namely, if
the ID range of the xstats stats item does not include the basic
stats item, the app can not obtain the corresponding xstats
statistics in hns3_dev_xstats_get_by_id.

Fixes: 8839c5e202f3 ("net/hns3: support device stats")
