I'm pretty sure there isn't at this point.

We'll need to elide setting ->rxhash for non-TCP packets.  I bet that
the ETH_FAST_PATH_RX_CQE_RSS_HASH_TYPE field might be usable to making
this decision, but if not in the worst case we'll need to parse the
VLAN/ETH and IP4/IP6 headers to figure out the protocol.

Damn, I'm so pissed off about this.  This ruins everything!

How damn hard is it to add two 16-bit ports to the hash regardless of
protocol?
