Subject[PATCH AUTOSEL 4.9 21/28] net: hns: Use NAPI_POLL_WEIGHT for hns driver
Date
From: Yonglong Liu <liuyonglong@huawei.com>

[ Upstream commit acb1ce15a61154aa501891d67ebf79bc9ea26818 ]

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.
