            Bug ID: 1253
           Summary: [dpdk-23.07] vf_offload/test_tso_tunnel: IPv6/UDP/GTPU
                    packet of iavf cannot be forwarded in 32bit
           Product: DPDK
           Version: 23.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: testpmd

Target Milestone: ---

Environment
OS: Ubuntu 22.04.2 LTS/5.15.0-70-generic
DPDK version: dpdk-23.07-rc1: 050de60d8a5cef8b7c10b4471905ca8bf69d670e
Compiler: gcc version 11.3.0
NIC hardware: Ethernet Controller E810-XXV for SFP 159b
NIC driver: ice-1.12.0_rc135_1_g7290fc452_dirty
NIC firmware: 4.30 0x80019922 1.3403.0
ddp: ice comms 1.3.45.0

Test Setup
1.Bind the iavf port to dpdk driver
echo 1 > /sys/bus/pci/devices/0000\:31\:00.0/sriov_numvfs echo 1 > /sys/bus/pci/devices/0000\:31\:00.1/sriov_numvfs ip link set ens5f0 vf 0 spoofchk off
ip link set ens5f1 vf 0 spoofchk off ./usertools/dpdk-devbind.py -b vfio-pci 0000:31:01.0 0000:31:11.0

2.build dpdk
export CFLAGS=-m32
export PKG_CONFIG_LIBDIR=/usr/lib/i386-linux-gnu/pkgconfig/ CC=gcc meson -Denable_kmods=True -Dlibdir=lib --default-library=static i686-native-linuxapp-gcc
ninja -C i686-native-linuxapp-gcc

3.launch testpmd
i686-native-linuxapp-gcc/app/dpdk-testpmd -l 0-7 -n 1 -- -i --portmask=0x3
--enable-rx-cksum --max-pkt-len=9000

start

4. Send packet on tester
ifconfig ens160f0 mtu 9000 sendp([Ether(dst="D6:5B:05:90:7C:E0",src="52:00:00:00:00:00")/IPv6(src = "FE80:0:0:0:200:1FF:FE00:200", dst = "3555:5555:6666:6666:7777:7777:8888:8888")
/ UDP(dport = 2152) / GTP_U_Header(gtp_type=255, teid=0x123456)/IPv6(src="FE80:0:0:0:200:1FF:FE00:200", dst="3555:5555:6666:6666:7777:7777:8888:8888")/TCP(sport=1021,dport=1021)/Raw(RandString(size=8500))], iface="ens160f0", count=1000)

app/testpmd: fix GTP L2 length in checksum engine

GTP header can be followed by an optional 32 bits extension.

But, l2_len value statically set to RTE_ETHER_GTP_HLEN which is defined to be
(sizeof(struct rte_udp_hdr) + sizeof(struct rte_gtp_hdr))

This fixes the l2_len to take into consideration the extension size.

Fixes d8e5e69f3a9b ("app/testpmd: add GTP parsing and Tx checksum

offload")
