Generic Routing Encapsulation (GRE) is a tunneling protocol developed by Cisco Systems that can encapsulate
a wide variety of network layer protocols inside virtual point-to-point links over an Internet Protocol network.
Fortville support GRE packet detecting, checksum computing and filtering.

+
+Generic Routing Encapsulation (GRE) is a tunneling protocol developed by Cisco Systems that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links over an Internet Protocol network.
+Fortville support GRE packet detecting, checksum computing and filtering.

+Test Case 1: GRE ipv4 packet detect

+Start testpmd and enable rxonly forwarding mode::
+    testpmd -c ffff -n 4 -- -i --txqflags=0x0
+	testpmd> set fwd rxonly
+	testpmd> set verbose 1
+	testpmd> start
+ 
+Send packet as table listed and packet type match each layer.

+Test Case 3: GRE packet filter
+============================

+	testpmd> set fwd rxonly
+	testpmd> set nbcore 4

+	         0.0.0.0 1 ipingre iip 0 3
+ 
+Send packet inner ip address matched and check packet recevied by queue 3.

+
+Test Case 4: GRE packet chksum offload
+====================================
+Start testpmd with hardware checksum offload enabled::
+    testpmd -c ff -n 3 -- -i --txqflags=0x0 --enable-rx-cksum  --port-topology=loop
+	testpmd> set verbose 1

+	testpmd> csum set tcp hw 0
+	testpmd> csum parse_tunnel on 0
+	testpmd> start
+ 
+Send packet with wrong outer IP checksum and check forwarded packet IP
+checksum is correct.
+	Ether()/IP(chksum=0x0)/GRE()/IP()/TCP()
+
+Send packet with wrong inner IP checksum and check forwarded packet IP
+checksum is correct.

+Send packet with wrong inner TCP checksum and check forwarded packet TCP
