probably ;)

Also, is IGB really using the ports in the rss for UDP packets ?

Not by default.  The default is to only hash on the IP header for UDP
packets.

As such the default would only be setting the l4_rxhash on TCP frames
only.  The user would have to specifically request L4 port hashing for
UDP via the "ethtool -N" command for configuring rx-flow-hash.

So you should rewrite this patch ?

Or have I missed something ?
