Thanks for the patch
This approach will not work for the userspace datapath
Few issues off the top of my head:
1/ packet-out frees the packet (which is a fragment in this case)
after completion
hence multiple packet-outs need to be part of a single Openflow
bundle command as in other similar tests
This test involves 2 fragments for the first 2 packets.
2/ Userpsace datapath checks UDP checksums; for V6 packets, they need
to always be correct and they are not presently
3/ UDP header lengths cannot be larger than the memory allocated for
the packet, else sanity checking will filter
out the packet
Alternatively, if you want to use this simplified approach, you can
disable the test for the userspace datapath.
There's no reason that I know of to run this test in the userspace
datapath. It should be disabled.
How do you do that?
