i210is with SGMII

Hi,

we are developing a board with I210is using SGMII to a broadcom switch BCM53134O. We are using the lates image "Dev_Start_I210_SerdesKX_NOMNG_8Mb_A2_3.25_0.03.bin" and have set the Extende device control Register to SGMII 0x129400C0 (Bit23:22). The Linux Driver is 5.33

Ethtool is reporting and we got no connection to the Broadcom interface

Settings for eth1:

        Supported ports: [ FIBRE ]

        Supported link modes:   100baseT/Full

                                1000baseT/Full

        Supports auto-negotiation: Yes

        Advertised link modes:  Not reported

        Advertised pause frame use: Symmetric

        Advertised auto-negotiation: Yes

        Speed: Unknown!

        Duplex: Unknown! (255)

        Port: FIBRE

        PHYAD: 0

        Transceiver: external

        Auto-negotiation: on

        Supports Wake-on: pumbg

        Wake-on: g

        Current message level: 0x00000007 (7)

        Link detected: no

I'd expect that the Port should switch from FIBRE to SGMII.

Is there something else which needs to be ajusted

regards
