From: Huisong Li <[email protected]>
The hash key length of hns3 driver is obtained from firmware. If the
length isn't a multiple of HNS3_RSS_HASH_KEY_NUM (16), the last part
of hash key will be truncated.
Fixes: 4a7384e3c34d ("net/hns3: refactor set RSS hash algorithm and key
interface")
Fixes: c37ca66f2b27 ("net/hns3: support RSS")
