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.
