Hello,  
We are experiencing issues when attempting to use a 10GTek ASF-GE-T SFP module. The steps and results are as follows:

We execute the command:  
`> sudo ls-addni dpmac.8`

This completes without any error messages.

However, when we try to bring up the interface `eth1` with:  
`> dchclient eth1`

we encounter the following error output:

```auto
fsl_dpaa2_eth dpni.1: Adding to iommu group 2
fsl_dpaa2_eth dpni.1: Probed interface eth1
fsl_dpaa2_eth dpni.1 eth1: configuring for inband/10gbase-r link mode
fsl_dpaa2_eth dpni.1 eth1: validation of inband/sgmii with support 0000000,00000200,000062e0 failed: -22
sfp sfp-1: sfp_add_phy failed: -22

```

The SFP module we are using is 10GTek ASF-GE-T.

We tested with last stable image (lsdk-21.08, 2025-05-06\_953878b) and last available build (2025-05-20\_b88bd5d/) with the same result

Please advise on any additional configuration or compatibility checks we should perform. Let us know if you require further details.

Best regards,
