  From: Xuan Ding <xuan.ding@intel.com>

This patch adds header split configuration in testpmd. The header split
feature is off by default. To enable header split, you need:
1. Configure Rx queue with rx_offload header split on.
2. Set the protocol type of header split.

Command for set header split protocol type:
testpmd> port config <port_id> header_split mac|ipv4|ipv6|l3|tcp|udp|sctp|
		    l4|inner_mac|inner_ipv4|inner_ipv6|inner_l3|inner_tcp|
		    inner_udp|inner_sctp|inner_l4
