Subject: [PATCH 0/17] net: Add rxhash utility hash functions

This patch series introduce skb_set_rxhash and skb_clear_rxhash
which are called to set the rxhash (from network drivers) and
to clear the rxhash. This API should be used instead of updating
fields in the skbuff directly.

Verified that the drivers compiled with the changes (verified
bnx2x is operational).

By my count 15 NIC drivers set the rxhash, but only two of them
mark the hash as L4. It looks like several of those have capability
do determine an L4 hash was done.
