I mentioned Ales in my notes but forgot to CC him in my reply. Whoops.
I've added him now :)

The patch, when 'persistent' flag is specified, makes the IP selection
in a range persistent across reboots.

The userspace conntrack only supported hash for port selection.
With the patch, both userspace and kernel datapath support the random
flag.
The default behavior remains the same, that is, if no flags are
specified, hash is selected.

Bleep bloop. Greetings Martin Kalcok, I am a robot and I have tried out your
patch.
Thanks for your contribution.
I encountered some error that I wasn't expecting. See the details below.

Bleep bloop. Greetings Ales Musil, I am a robot and I have tried out your
patch.
Thanks for your contribution.
I encountered some error that I wasn't expecting. See the details below.
git-am:
error: sha1 information is lacking or useless (tests/ovn.at).
error: could not build fake ancestor
Thank you Ales and Xavier.
I applied patches 1-26 to main as is. The patches to remove table
numbers from comments can be uploaded as a separate series or part of v3
for patches 27-29.

The macro had two issues:
- It never used the third (optional) argument (command such as trim_zeros).
- The default command was wrong, causing the test to always succeed.

Open vSwitch module accepts actions as a list from the netlink socket
and then creates a copy which it uses in the action set processing.
During processing of the action list on a packet, the module keeps a
count of the execution depth and exits processing if the action depth
goes too high.
Add a test case into the netlink checks that will show the number of
nested action recursions won't exceed 16. Going to 17 on a small
clone call isn't enough to exhaust the stack on (most) systems, so
it should be safe to run even on systems that don't have the fix
applied.

The ovs module allows for some actions to recursively contain an action
list for complex scenarios, such as sampling, checking lengths, etc.
When these actions are copied into the internal flow table, they are
evaluated to validate that such actions make sense, and these calls
happen recursively.
