From: Russell King <redacted> Some GPON SFP modules (e.g. Ubiquiti U-Fiber Instant) have set both SFP_OPTIONS_LOS_INVERTED and SFP_OPTIONS_LOS_NORMAL bits in their EEPROM. Such combination of bits is meaningless so assume that LOS signal is not implemented. This patch fixes link carrier for GPON SFP module Ubiquiti U-Fiber Instant. Signed-off-by: Russell King <redacted> Signed-off-by: Pali Rohár <pali@kernel.org>Reviewed-by: Andrew Lunn <andrew@lunn.ch>I'd like to send this patch irrespective of discussion on the other patches - I already have it committed in my repository with a different description, but the patch content is the same. Are you happy if I transfer Andrew's r-b tag, and convert yours to an acked-by before I send it? I'd also like to add a patch that allows 2.5G if no other modes are found, but the bitrate specified by the module allows 2.5G speed - much like we do for 1G speeds.Russell, should I send a new version of patch series without this patch?
I think there's some work to be done for patch 1, so I was thinking of sending this with another SFP patch. It's really a bug fix since the existing code doesn't behave very well if both bits are set - it will toggle state on every RX_LOS event received irrespective of the RX_LOS state. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
