Thanks Ales,

This looks good to me.

Acked-by: Mark Michelson <mmich...@redhat.com>

On 5/18/23 09:26, Ales Musil wrote:
Bump submodule to v2.17.6 specifically for:
1989caf9ea5e ("ovsdb-idl: Preserve references for rows deleted in same IDL run as 
their insertion.")

with additional test from:
c18415d5ae72 ("ovs: Bump submodule to tip of branch-3.0 and add related test")

This commit is combination of multiple cherry-picks
because they woldn't pass CI standalone.
The parts of following commits are included in this one:
ebd6bdd3e343 ("tests: Fix tests/check_acl_log.py outputs.")
e06c34255662 ("tests: Avoid matching on the OVS flow key contents.")
