82574l gigabit adapter limited to 100Mbps

[Schan721]

Hello Intel,

We have designed a board that uses Intel's 82574l Gigabit ethernet controller,

integrated with SOC(running on Debian Gnu/linux).

Issues :

1.The chip 82574l worked well only under 100Mbps speed.

2. When forced to work on Gbps it automatically switched to fast Ethernet speed 10/100Mbps.

PFA of ethernet schematics.

Could there be any specific drivers for the Chip to work @ 1Gbps?

We used CAT5e Cable.

Looking forward for a solution.

Thanks in advance,

saravana.
