I'm not sure,
This is only for some of the chip simulation environments that don't have an NVRAM.
Not for a real chip.

OK (we all love the police. funny that checkpatch.pl did not find this)

This is still not enabled by default.
We are limited to 16 queues and they are rather expansive, so I'm not sure what would be best.
Can you please give me pointers to examples?
In any case on the TX side you don't need more than one per cpu.

OK

Thanks...

I will send the fixes as patches.
The reset change needs to be very carefully tested so this will only happen early next week.

Thanks,
Eliezer
