Hello
I am looking for help with bpi-r4 and SFP+ -LRB 10G fiber transceiver - tx1330/rx1270
Problem looks like after software reboot router via ssh with command reboot. I totally lost connection to my ISP.
ethtool -m and ethtool -S, ethtool commands says that everything is very good. But it can’t establish connection anymore. It sends packet but receive 0
i am even thinkin about erased firmware of this transiver becouse sound very strange how reboot can affect physical stability
Temperatures was good all time
And now physicall power off router, unplugging transiever or fiber cable nothing helps
Here is few logs:

Have bought a SFP+ module ONTi ONT-C11TE-R01
When I try to use it with the latest snapshot it beaks Luci UI … and do freezes in ssh console if I try to call ifconfig.
dmesg shows that system identified it as OEM SPF-10G-T rev 02 … and nothing else
Any ideas how to deal with it?
PS
It seams that the problem with autoneg … after some time it finally interface starts but it shows 10G (ethtool eth1 shows “Speed: 10000Mb/s”) where a client has only 2.5G NIC card. And in dmesg “mtk_soc_eth 15100000.ethernet eth1: selection of interface failed, advertisement 00,00000000,00000000,00006248”
Hello, I’m planning to buy this module to replace my Alcatel G-010S-P which completely lose connection if bpi-r4 perform a soft reboot. Had to re-plug power cable to make it work again.
Can you confirm that your router has no problem establishing PPPoE through this Huawei one after a ‘reboot’ command? Thanks.
The patch is afaik (if i understood correctly) only for sfp not supporting in-band-management (daniel told me only some with broadcom phy).
The in-band-management itself should only report link-state,not speed,duplex, etc. Kernel needs to know supported speeds from eeprom,if eeprom does not contain some speeds we have added them (or forced to one) with quirks.
Phylink’s handling of in-band has been deficient for a long time, and
people keep hitting problems with it. Notably, situations with the way-
to-late standardized 2500Base-X and whether that should or should not
have in-band enabled. We have also been carrying a hack in the form of
phylink_phy_no_inband() for a PHY that has been used on a SFP module,
but has no in-band capabilities, not even for SGMII.
When phylink is trying to operate in in-band mode, this series will look
at the capabilities of the MAC-side PCS and PHY, and work out whether
in-band can or should be used, programming the PHY as appropriate.
net: phylink: add negotiation of in-band capabilities
Support for in-band signalling with Serdes links is uncertain. Some
PHYs do not support in-band for e.g. SGMII. Some PCS do not support
in-band for 2500Base-X. Some PCS require in-band for Base-X protocols.
Simply using what is in DT is insufficient when we have hot-pluggable
PHYs e.g. in the form of SFP modules, which may not provide the
in-band signalling.
In order to address this, we have introduced phy_inband_caps() and
pcs_inband_caps() functions to allow phylink to retrieve the
capabilities from each end of the PCS/PHY link. This commit adds code
to resolve whether in-band will be used in the various scenarios that
we have: In-band not being used, PHY present using SGMII or Base-X,
PHY not present. We also deal with no capabilties provided.
So, I understood, here we can tell phylink the pcs does not support inband at 2500-basex and have phylink negotiate if it can link PCS to PHY using this limitation.
I did the same in my crude patch, but this is much better ofcourse. He mentioned a while back he was working on it, so I did not go any further with my patch, waiting for his work to be mainlined.
I have exactly the same issue with this module. After a soft or hard reboot it would occasionally lose link until unplugged and replugged into the router. Like this time:
[ 96.130345] sfp sfp1: module OEM SFP-2.5G-T-R-RM rev 1.0 sn 2405070065 dc 240507
[ 100.866956] mtk_soc_eth 15100000.ethernet eth2: Link is Up - 2.5Gbps/Full - flow control rx
[ 158.718349] mtk_soc_eth 15100000.ethernet eth2: Link is Down
tI am connected using PPPoE at the moment.
The only issue I had to do is create a script to restart the LAN port after 120 seconds, after initiation. Through investigation I realized that there is a normal delay in establishing the PPPoE connection, creating the possibility of not propagating IPv6 PDs through the LAN port, because it started before the creation of PPP0E_WANv6 was established. Sometimes it doesn’t even propagate IPv4.
But this is independent of whether I used the SPF or UNO module, I always needed this trick.
It is not yet a definitive solution to the problem, but it is what I have at the moment.
Call at startup:
sh /etc/ifup_delayed.sh
Script:
#!/bin/sh
sleep 120
ifup lan
So the establishment with PPPoe is normal, my problem is in DHCP propagation.
