[PATCH net 06/10] net: hns: fix return value of the function about rss

From: Yisen Zhuang
Date: Mon Mar 21 2016 - 06:50:23 EST


From: Kejian Yan <yankejian@xxxxxxxxxx>

Both .get_rxfh and .get_rxfh are always return 0, it should return result
from hardware when getting or setting rss. And the rss function should
return the correct data type.
