You mean the i.MX6 SoC? Yeah, that one is limited to 540 MBit/s by design.

In comparison to the i.MX series the LayerScape models are supposed to be network \
processors. So, even though they have a tendency to fuck things up, I don't think \
they also do that on something that already worked with PPC for some time.

I have not yet run performance tests on the TWR-LS1021A.
