ixgbe: drop support for UDP in RSS hash generation
This change removes UDP from the supported protocols for RSS hashing. The
reason for removing this protocol is because IP fragmentation was causing a
network flow to be broken into two streams, one for fragmented, and one for
non-fragmented and this in turn was causing out-of-order issues.
