[dpdk-dev] [PATCH v3 4/4] net/hns3: fix RSS configuration when empty RSS type

["Wei Hu (Xavier)" <xavier.huwei@huawei.com>]

From: Lijun Ou <oulijun@huawei.com>

According to the definition of RSS types of action attributes from
testpmd, the driver will not disable RSS but instead requests the
unspecified "best-effort" settings when upper application call
rte_flow_create API function to create flow using empty RSS types.

As a result, here use the default RSS types when RSS types is empty.

Fixes: c37ca66f2b27 ("net/hns3: support RSS")
