netdev: simple_tx_hash shouldn't hash inside fragments
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. Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: David S.
