Description Eelco Chaudron 2022-02-28 11:09:31 UTC 
We recently added to OVS support to actually print extended ack
messages received from the kernel:
  https://github.com/openvswitch/ovs/commit/4a6a4734622e42367faf39cd3938bc8a57786282
but I'm not sure if anyone started to add more messages to the kernel
itself.

In general, we need to find all the places where execute/put/get/del
requests returns an error inside the kernel and add some meaningful
extack message to the netlink reply at that point.  It's kind of a
lot of work, but it should be very beneficial for anyone who tries
to debug this kind of in-kernel problems or miscommunication between
OVS kernel and userspace.
