1. reload ice
rmmod ice && modprobe ice
2. create 1 vf and set vf echo 1 >

ip link set ens802f0np0 vf 0 trust on
ip link set ens802f0np0 vf 0 spoofchk off
modprobe vfio && modprobe vfio-pci
./usertools/dpdk-devbind.py -b vfio-pci 0000:af:01.0
3. start testpmd x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-2 -n 4 -a
0000:af:01.0,cap=3Ddcf  -- -i --enable-rx-cksum
4. set testpmd
set verbose 1
set fwd csum
set promisc 0 on
port stop all
csum set ip hw 0
csum set udp hw 0
csum set tcp hw 0
csum set sctp hw 0
csum set outer-ip hw 0
csum set outer-udp hw 0

    net: fix GTP packet parsing

    After parsing the GTP packet header, the next protocol type should
    be converted from RTE_GTP_TYPE_IPV4/IPV6 to RTE_ETHER_TYPE_IPV4/IPV6.
    Otherwise, the next protocol cannot be parsed.

    Bugzilla ID: 1672
    Fixes: 64ed7f854cf4 ("net: add tunnel packet type parsing")
