I am trying to enable RGMII(1Gbps) on our custom board which uses BCM54213 PHY.
I am able to communicate with 100BaseT speed but not with 1000BaseT speed.
I verified the **filtered** register (reg 9) and the phy advertises as 1000 BaseT.
I am sure that my network and cables supports 1Gbps(verified with other board which has different PHY).
Is there any special configuration required for the link communication to support 1Gbps. Any info would be helpful.
