Currently simple_tx_hash is hashing inside of udp fragments. As a result
packets are getting getting sent to all queues when they shouldn't be.
This causes a serious performance regression which can be seen by sending
UDP frames larger than mtu on multiqueue devices. This change will make
it so that fragments are hashed only as IP datagrams w/o any protocol
information.
