[PATCH V2 net-next 03/12] net: hns3: modify the VF network port media type acquisition method

[Huazhong Tan]

From: liuzhongzhu <liuzhongzhu@xxxxxxxxxx>

Method for obtaining the media type of the VF network port periodically,
regular tasks will not run until the network port UP. When the network
port is DOWN, the network port cannot obtain the media type.
Modifies the madie type obtained when initializing the VF network port.
