Avoid reading link modes from management firmware every time when `ethtool_get_link_ksettings` is called, only communicate with management firmware when necessary like we do for eth_table info. This change can ease the situation that when large number of vlan sub-interfaces are created and their information is requested by some monitoring process like PCP [1] through ethool ioctl frequently.
