[U-Boot-Users] Intel 82551IT ethernet controller phy loopback in monitor level ??

Hi all

In U-boot my ethernet controller PMC card with 82551It is working perfectly..

My customer needs to test the controller in monitor level also..

I have initialized 82551It and i can able to access phy thru mac..

Did anybody tried loopback(phy loopback) in monitor level for 82551It ?

Thanks
