net: hns3: differentiate autoneg default values between copper and fiber
Fix a link loss issue during driver initialization on optical ports
connected to forced-mode (non-autoneg) remote switches.
Previously, during driver probe or initialization, hclge_configure()
blindly hardcoded hdev->hw.mac.req_autoneg to AUTONEG_ENABLE for all
media types. While this is necessary for copper (BASE-T) ports to
establish a link, many high-speed optical (fiber) ports in data
centers are connected to switches running in forced mode (fixed speed,
autoneg disabled). Forcing autoneg on these optical ports during
initialization causes a permanent link failure since the remote end
refuses to respond to autoneg pulses.
Fix this by implementing media-type differentiated initialization in
hclge_init_ae_dev(). Copper ports continue to default to
AUTONEG_ENABLE, while optical ports strictly inherit the preset
autoneg status pre-configured by the firmware (hdev->hw.mac.autoneg),
preserving native compatibility with forced-mode network environments.
