[PATCH net-next 1/2] net: hns3: fix sparse: warning when calling hclge_set_vlan_filter_hw()

[Huazhong Tan]

From: Jian Shen <shenjian15@huawei.com>

The input parameter "proto" in function hclge_set_vlan_filter_hw()
is asked to be __be16, but got u16 when calling it in function
hclge_update_port_base_vlan_cfg().

This patch fixes it by converting it with htons().

[PATCH net-next 2/2] net: hns3: fix for vport->bw_limit overflow problem

[Huazhong Tan]

From: Yunsheng Lin <linyunsheng@huawei.com>

When setting vport->bw_limit to hdev->tm_info.pg_info[0].bw_limit
in hclge_tm_vport_tc_info_update, vport->bw_limit can be as big as
HCLGE_ETHER_MAX_RATE (100000), which can not fit into u16 (65535).

So this patch fixes it by using u32 for vport->bw_limit.
