Subject: [PATCH ethtool-next] netlink: settings: add two link extended substates of bad signal integrity

Add two link extended substates of bad signal integrity available in the
kernel.

ETHTOOL_LINK_EXT_SUBSTATE_BSI_SERDES_REFERENCE_CLOCK_LOST means the input
external clock signal for SerDes is too weak or lost.

ETHTOOL_LINK_EXT_SUBSTATE_BSI_SERDES_ALOS means the received signal for
SerDes is too weak because analog loss of signal.
