Thank you for testing this. Unfortunately, I have no P-series hardware,
so I was unable to test the 10gec/dtsec parts of this conversion. I had
hoped that this would get tested by someone with the hardware (at NXP)
before now, but it seems you get to be the "lucky" first user.

I see you have labeled one of your kernels as supporting QEMU.  Do you
happen to have instructions for running Linux on QEMU?

Can you try the following patch. I think my mail client will mangle it,  
so I have also attached it to this email.

Hi Sean,

Thanks a lot for your answer.

I use the virtio-net device in a virtual e5500 QEMU/KVM HV machine. [1] [2]

I will test your patch as soon as possible.

Thanks,
Christian
