Subject: ethtool: add two link extended substates of bad signal integrity
Patch-mainline: v5.15-rc1
Git-commit: 5b4ecc3d4c4aab8d002fe6358885c10e7b57e432
References: bsc#1190336

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.
