Subject: net: hns3: modify the VF network port media type acquisition method
Patch-mainline: v5.2-rc1
Git-commit: 9c3e713020fc8e08e02d6756b401125ab5cb702c
References: bsc#1104353 FATE#326415 bsc#1137201

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 media type obtained when initializing the VF network port.
