[PATCH net-next 4/4] net: hns3: fix for FEC configuration

[Huazhong Tan <tanhuazhong@huawei.com>]

From: Jian Shen <shenjian15@huawei.com>

The FEC capbility may be changed with port speed changes. Driver
needs to read the active FEC mode, and update FEC capability
when port speed changes.

Fixes: 7e6ec9148a1d ("net: hns3: add support for FEC encoding control")
