We have a warning[1] in dmesg shows hns register napi as weight 256 but not recommended. According to this commit[2] we shall use weight 64 as suggested.

To cherry-pick this makes hns driver has reasonable weight

    net: hns: Use NAPI_POLL_WEIGHT for hns driver

    When the HNS driver loaded, always have an error print:
    "netif_napi_add() called with weight 256"

    This is because the kernel checks the NAPI polling weights
    requested by drivers and it prints an error message if a driver
    requests a weight bigger than 64.

    So use NAPI_POLL_WEIGHT to fix it.
