<pre class="bz_comment_text">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

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

commit dd827fa42a30a9b0aa87a1d5614af83ea32b19e0

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")
