Hi,
I'm facing a strange behavior of the Linux driver ixgbe.
I'm running Debian Trixie with kernel 6.6.15.
The problem is if I'm using a RJ45 1Gbit SFP in any of these ports or an SFP from StarBit / UBNT vendor, on driver loading I'm getting this message:
[ 1033.656870] ixgbe 0000:0c:00.0: failed to load because an unsupported SFP+ or QSFP module type was detected.
[ 1033.657212] ixgbe 0000:0c:00.0: Reload the driver after installing a supported module.
But the funny part comes if I'm reloading the driver with the SFP unplugged or just add the PCIe device under the driver for the specific interface without SFP inserted and then plug the SFP back. Now everything is working perfect:
# echo "0000:0c:00.0" > /sys/module/ixgbe/drivers/pci\:ixgbe/bind
# dmesg | grep 0000:0c:00.0

The interface is active in the system.
Replug the SFP, no errors. Checking the SFP parameters:

I tried to use allow_unsupported_sfp=1 but still without success.
Looking in the ixgbe code I'm seeing a similar code twice:
/* Verify supported 1G SFP modules */
if (comp_codes_10g == 0 &&
!(hw->phy.sfp_type == ixgbe_sfp_type_1g_cu_core1 ||
hw->phy.sfp_type == ixgbe_sfp_type_1g_cu_core0 ||
hw->phy.sfp_type == ixgbe_sfp_type_1g_lx_core0 ||

hw->phy.sfp_type == ixgbe_sfp_type_1g_sx_core0 ||
hw->phy.sfp_type == ixgbe_sfp_type_1g_sx_core1)) {
hw->phy.type = ixgbe_phy_sfp_unsupported;
return -EOPNOTSUPP;
}
/* Anything else 82598-based is supported */
if (hw->mac.type == ixgbe_mac_82598EB)
return 0;
hw->mac.ops.get_device_caps(hw, &enforce_sfp);
if (!(enforce_sfp & IXGBE_DEVICE_CAPS_ALLOW_ANY_SFP) &&
!(hw->phy.sfp_type == ixgbe_sfp_type_1g_cu_core0 ||
hw->phy.sfp_type == ixgbe_sfp_type_1g_cu_core1 ||
hw->phy.sfp_type == ixgbe_sfp_type_1g_lx_core0 ||
hw->phy.sfp_type == ixgbe_sfp_type_1g_lx_core1 ||
hw->phy.sfp_type == ixgbe_sfp_type_1g_sx_core0 ||
hw->phy.sfp_type == ixgbe_sfp_type_1g_sx_core1)) {
/* Make sure we're a supported PHY type */
if (hw->phy.type == ixgbe_phy_sfp_intel)
return 0;
if (hw->allow_unsupported_sfp) {
e_warn(drv, "WARNING: Intel (R) Network Connections are quality tested using Intel (R) Ethernet Optics. Using untested modules is not supported and may cause unstable operation or damage to the module or the adapter. Intel Corporation is not responsible for any harm caused by using untested modules.\n");
return 0;
}
hw_dbg(hw, "SFP+ module not supported\n");
hw->phy.type = ixgbe_phy_sfp_unsupported;
return -EOPNOTSUPP;
}
return 0;
What I don't understand how allow_unsupported_sfp is ignored by the driver? And how is passing the checks after the driver is loaded?
Does anybody have any idea?
The StarBit SFPs are having EEPROM for Cisco switches.

Also I've notice when I'm trying to bring the interface up with such SFP the driver is removing the device interface from system with error unsupported SFP.

Hi @Dineshbabu
Is already mentioned in the title: Intel X553 on Atom C3758R. This CPU has 4x 10GbE X553 NICs builtin. Check the specs of the Atom C3000 series.
