[PATCH v2 1/5] net/hns3: fix never set MAC flow control

[Dongdong Liu]

From: Huisong Li <lihuisong at huawei.com>

When some hardware and firmware support speed auto-negotiation
but do not support flow control auto-negotiation, driver can
never successfully set MAC flow control by flow_ctrl_set() API.
So only tell user driver doesn't support flow control autoneg
when user enable it.

Fixes: 1f411e31a826 ("net/hns3: support flow control autoneg for copper port")
