Linux/DP83867IR: DP83867IR only works on 1000 Mbps

Part Number: DP83867IR

Tool/software: Linux

Good day! Can not get DP83867IR to 100 Mbps. It works only on 1000 Mbps. We can translate DP83867IR to 100 Mbps, but data exchange between DP83867IR and Zynq UltraScale + does not work.
I apologize for my English)

    Добрый день! Не удается получить DP83867IR до 100 Мбит / с. Работает только на 1000 Мбит / с. Мы можем перевести DP83867IR на 100 Мбит / с, но обмена данных нет.

    Hi Andrej,

    By PC, do you mean link partner that is connected to DP83867 via cat 5e cable?

    How to you put the PHY in 100Mbps mode? Do you force it to 100Mbps or let it autonegotiate?

    Does the link partner support 100Mbps operation? Does the PHY have a successful link up? You can check this by reading register 0x0001 or by observing LED_0.

    -Regards

    We connect to the R & H device, and the connection is established at 100 Mbps, and when connected via the D-link DGS-1008D switchboard, only 1000 Mbps works, even if we forcibly installed 100 Mbps, there is no connection to the switch.
