Ixgbe doesn't support the ipv4-frag and ipv6-frag flow types, remove them.
Ixgbe doesn't support configure flex mask on each kind of flow type, this
patch uses RTE_ETH_FLOW_UNKNOWN to specify global flex mask setting.
This patch also changes the string "raw" to "none" to indicate flex mask
setting unrelated with flow type in testpmd for ixgbe.
