Thanks for nice explaining!Yeah, CPU marked IXP425AD.
But i can't understand, really it is impossible to fix it(LE/BE conversion) in the NPE-ethernet driver?
Why not?
The B-step and later CPUs support a "data coherent" attribute bit in page table entries. This bit controls how the CPU views the LE memory area covered by the page table section entry. The networking support for NPE relies on this special view into memory, but the A-step CPUs cannot provide this.
I wouldn't say it is impossible to get around this, but it isn't worth the effort to support the original run of CPUs.
