rps: consistent rxhash
In case we compute a software skb->rxhash, we can generate a consistent hash : Its value will be the same in both flow directions. This helps some workloads, like conntracking, since the same state needs to be accessed in both directions. tbench + RFS + this patch gives better results than tbench with default kernel configuration (no RPS, no RFS) Also fixed some sparse warnings.
