I validated this modification on my x710 network card, but I found that
the outer UDP checksum of the transmitted packets is incorrect, leading
to communication abnormalities. I think it's necessary to disable the outer
UDP checksum because although the capability reported by DPDK
indicates
The outer checksum offloading API in DPDK is ambiguous and was
added by Intel folks with the assumption that any outer offloading
always goes with an inner offloading request.
With net/i40e and net/ice drivers, requesting outer ip checksum with a
tunnel context but no inner offloading request
