Subject: [PATCH V3 net-next 6/6] net: hns3: remove the way to set tx spare buf via module parameter

From: Hao Chen <chenhao288@...ilicon.com>

The way to set tx spare buf via module parameter is not such
convenient as the way to set it via ethtool.

So,remove the way to set tx spare buf via module parameter.
