From ad651d68cee75e9ac20002254c4e5d09ee67a84b Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Sun, 2 Apr 2023 12:44:37 +0100 Subject: [PATCH] net: sfp: add quirk enabling 2500Base-x for HG MXPD-483II The HG MXPD-483II 1310nm SFP module is meant to operate with 2500Base-X, however, in their EEPROM they incorrectly specify: Transceiver type : Ethernet: 1000BASE-LX ... BR, Nominal : 2600MBd Use sfp_quirk_2500basex for this module to allow 2500Base-X mode anyway. https://forum.banana-pi.org/t/bpi-r3-sfp-module-compatibility/14573/60 Reported-by: chowtom Tested-by: chowtom Signed-off-by: Daniel Golle Reviewed-by: Russell King (Oracle) Signed-off-by: David S.
