Irrespective of the type of the key used, the user would want to change the hash key if he/she is not satisfied with the effectiveness of the default hash-key in spreading the incoming flows evenly across the RSS queues.

Hi,

I would be happy to add support in setting the hash function in
addition to the hash key.

Mellanox NIC's have support in 2 hash functions: Toplitz and XOR.

Let me if you can add it to your patchset or would like me to send a
patch on top of yours to add it.

Thanks,
Amir
