Hello. We can't establish 1000M link between DP83867 and Dlink switch, while DP83867<-> Hirschmann switch 1000M link is ok, and DP83867 <-> PC (different network cards) 1000M link is ok. Dlink switch <-> PC link is also ok. DP83867's Registers dumps attached (linked case, no-link case, and no-cable(disconnected) case).
RX_ctrl pin strapped to mode1, but workaround is implemented in software (bit7 in reg 0x0031 cleared to 0).
