+Subject: ethtool: Fix SFF-8472 transceiver module identification
+
+According to table 5-1 in SFF-8472 Rev. 12.4, the Identifier Values for
+"GBIC" (01h) and "Module soldered to motherboard (ex: SFF)" (02h) are
+supported by the specification in addition to the current one.
+Therefore, adjust ethtool to invoke the SFF-8079 parser for them, which
+will in turn invoke the SFF-8472 parser if the transceiver module
+supports digital diagnostic monitoring.
+
+Without this patch, the EEPROM contents of such transceiver modules will
+be hex dumped instead of being parsed and printed in a human readable
+format.
+
+Fixes: 25b64c66f58d ("ethtool: Add netlink handler for getmodule (-m)")
