I have looked into this issue and have started implementing patches to the standard mv_cesa driver that will enable the TDMA engines to work with the CESA engines to off-load the processor. The problem I have run into is the documentation for the CESA/TDMA engines is missing details on how...					

I have noticed that if i use the sheevaplug's code for openRD (ie) /arch/arm/mach-kirkwood/sheevaplug-setup.c by setting the archNumber to 2097 then one ethernet port(eth0) works. Then i copied the pci init function call from the openrd file into the above mentioned file and PCI-Express also seem to be working fine....					

The mv_cesa driver doesn't use DMA, so performance is limited to 8MB/s (even less if the CPU is busy with other tasks). This makes quite a difference when (parts of) the hard disk is encrypted and/or when using IPSec.

Much higher throughputs should be possible when using TDMA: reading input (<800MB/s),...					

I have twice of OpenRD, one show the problem above with one of the two Ethernet interface working. The other, with the same code adaption didn't work. None of the two Ethernet interfaces start work. The log follows:

What steps will reproduce the problem?
Ethernet interface broken for Linux-2.6.35.5

What is the expected output? What do you see instead?
