[PATCH 2/2] net/hns3: fix cannot fully use hardware flow director table

[Jie Hai]

From: Dengdui Huang <huangdengdui at huawei.com>

The hns3 driver checks whether the flow rule is repeatedly inserted based
on rte_hash. Currently, the rte_hash extendable bucket table feature is not
enabled. When there are many hash conflicts, the hash table space cannot be
fully used. So the flow rule maybe cannot be inserted even if the hardware
flow director table there are still free. This patch fix it by enabling the
rte_hash extensible bucket table feature.
