I agree that this should be corrected atop the backports.
It would be great to see this SFP support upstreamed.
I have not tested SFP on OpenWrt master for some time, so I cannot blame a
change yet.
This is what I am seeing on ramips 760igs:
SFP (module, and driver LOS) has link detected, but this is not reflected by
the interface
(which is configured in OpenWrt as part of a bridge)
sfp: mtu 1500 qdisc fq_codel master br-wan
state DOWN qlen 1000
r16925+6-b721579842 master, plus my
SPI-NOR changes: https://github.com/openwrt/openwrt/pull/3271/commits
I do not remember these being looped in dmesg when I had working SFP:
sfp sfp1: SM: enter present:up:link_up event dev_up
sfp sfp1: SM: exit present:up:link_up
ethtool sfp

these cannot be forced on my current build:
