 Pattern: outer ipv4 + inner ipv4
 ================================
 
+GTPoGRE is imported in DPDK-21.02.
+The Ptype is parsed same as GTP packet, so they match gtp RSS rule.
+We just need to add the GTPoGRE packet to the packets check.
+we need to add GTPoGRE packet to "basic hit pattern packets",
+"hit pattern/defined input set" and "hit pattern/not defined input set".
+the GTPoGRE packet format in this pattern is to add::
+
+    IP(proto=0x2F)/GRE(proto=0x0800)/
+
+after Ether layer, before IP layer, just like::
+
+    sendp([Ether(dst="00:11:22:33:44:55")/IP(proto=0x2F)/GRE(proto=0x0800)/IP()/UDP(dport=2152)/GTP_U_Header(gtp_type=255, teid=0x123456)/GTPPDUSessionContainer(type=0, P=1, QFI=0x34)/IP(dst="192.168.0.1", src="192.168.0.2")/("X"*480)],iface="enp134s0f0")
