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.

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.

Ok! So I will fix what is needed for patch 1, send it with patch 3 as
next version and let patch 2 to you.
