I tested disabling super pages and I get the same behavior. I verified the
sysctl bit and it was disabled.
I tested disabling tso (as suggested on mailing list, despite tso was already 
disabled) and I get the same behavior.

I would love to implement the API to load this firmware blob, to test it. It
could take some time but it seems doable. Firmware blobs are not GPLed, they're
distributed as binary permitted by the vendor. BTW, I would just test it.

In parallel, I'll try to understand where this new rx_desc are written, if
there's a logical connection with the loaded DMA maps.
