Hi all,
I'm using ovs-dpdk(ovs:2.17.1, dpdk:21.11.1).
Now I found a BUG that ovs crash and could NOT fix again after set
request_mtu.
1. How to reproduce and my Analysis:
```
# start ovs and add bridge and port and openflow
[root@bogon ~]# ovs-vsctl show

All informations required for checksum offloading can be deducted by
already tracked dp_packet l3_ofs, l4_ofs, inner_l3_ofs and inner_l4_ofs
fields.
Remove DPDK specific l[2-4]_len from generic OVS code.
netdev-dpdk code then fills mbuf specifics step by step:
- outer_l2_len and outer_l3_len are n
In a typical setup like:
guest A <-virtio-> OVS A <-vxlan-> OVS B <-virtio-> guest B
TSO packets from guest A are segmented against the OVS A physical port
mtu adjusted by the vxlan tunnel header size, regardless of guest A
interface mtu.
As an example, let's say guest A and guest B mtu are set t
Every L3, L4 checksum offload or TSO requires a (outer) L3 length to be
provided.
This length is computed via dp_packet_l4(pkt) that is always set when
such offloads are requested in OVS.
Getting a th == NULL is a bug in OVS, so an assert() is more appropriate.
Besides, filling l4_len and tso_segs
If outer checksum is not supported and OVS already set L3/L4 outer
checksums in the packet, no outer mark should be left in ol_flags
(as it confuses some driver, like net/ixgbe).
l2_len must be adjusted to account for the tunnel header.

Same as the commit 6f93d8e62f13 ("netdev-dpdk: Disable outer UDP checksum
offload for ice/i40e driver."), disable outer UDP checksum and related
offloads for net/iavf.

Note:
The outer checksum offloading API in DPDK is ambiguous and was
implemented by Intel folks in their drivers with the assumption that
any outer offloading always goes with an inner offloading request.
With net/i40e and net/ice drivers, in the case of encapsulating a ARP
packet in a vxlan tunnel (whi
