Subject: [PATCH net-next 2/4] net: hns3: remove add/del_tunnel_udp in hns3_enet module
Date: Wed, 9 May 2018 17:24:39 +0100	[thread overview]
Message-ID: <20180509162441.18068-3-salil.mehta@huawei.com> (raw)
In-Reply-To: <20180509162441.18068-1-salil.mehta@huawei.com>

From: Yunsheng Lin <linyunsheng@huawei.com>

The add/del_tunnel_udp is not implemented in hclge_main moulde,
the NETIF_F_RX_UDP_TUNNEL_PORT feature bit is added automatically
by stack when ndo_udp_tunnel_add is not null in dev->netdev_ops.

This patch removes the add/del_tunnel_udp related function, for
we do not support this feature now.
