Test Setup
Steps to reproduce
List the steps to reproduce the issue:
1. build dpdk
# rm -rf x86_64-native-linuxapp-gcc
# CC=gcc meson --werror -Denable_kmods=True  -Dlibdir=lib
-Dc_args='-DRTE_EAL_IGB_UIO=1' --default-library=static
x86_64-native-linuxapp-gcc
# ninja -C x86_64-native-linuxapp-gcc -j 70
2.lanch app
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd  -l 32,33,34,35,18 -n 4  
--file-prefix=dpdk_28921_20210902221900   -- -i --portmask=0x3
--enable-rx-cksum
3. dut set
vlan set filter off 0
set fwd csum
port stop all
csum set outer-ip hw 1
port start all
port stop all
csum set udp hw 1
port start all
port stop all
csum set tcp hw 1
port start all
port stop all
csum set sctp hw 1
port start all
csum parse-tunnel on 1
rx_vxlan_port add 4789 0
rx_vxlan_port add 4789 1
port stop all
csum set outer-ip sw 0
port start all
port stop all
csum set outer-ip sw 1
port start all
start
4. tester send packet
sendp([Ether(src='00:00:10:00:00:00',
dst='3c:fd:fe:b8:97:64')/IPv6(src='fe80::', dst='fe80::1')/UDP(sport=63,
dport=4789)/VXLAN(vni=1)/Ether(src='00:00:20:00:00:00',
dst='00:00:20:00:00:01')/IP(src='192.168.2.1',
dst='192.168.2.2')/UDP()/Raw(load=b'XXXXXXXXXXXXXXXXXX')],iface="ens2f0",count=1,inter=0,verbose=False)


Show the output from the previous commands:

After the dut receives the packet, it does not forward

app/testpmd: fix check without outer checksum

Donot use outer metadata when neither outer ip checksum nor
outer udp checksum is enabled. PMD's will ignore the
outer_l2_len and outer_l3_len in cases where none of
the outer checksum is enabled and hence only l2_len and
l3_len will be used to calculate the offsets for L2 or L3
header.
