I tested netplan.io 0.107.1-3ubuntu0.22.04.2 from jammy-proposed, all looking
good!
The intermittent failures reported in comment #12 are resolved.
First of all, the eswitch/switchdev functionality is not available on Jammy's
GA 5.15 kernel,
so I upgraded to the HWE kernel and installed Netplan from proposed:
ubuntu@akis:~$ sudo devlink dev eswitch show pci/0000:86:00.0
kernel answers: Operation not supported
ubuntu@akis:~$ sudo apt-get install --install-recommends linux-generic-hwe-22.04
ubuntu@akis:~$ uname -a
Linux akis 6.8.0-51-generic #52~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon Dec 9

ubuntu@akis:~$ sudo apt install -t jammy-proposed netplan.io
ubuntu@akis:~$ apt list *netplan*

Next, I identified the Mellanox ConnectX-5 NIC (enp134...0/1) and confrimed
that LAG is disabled:
ubuntu@akis:~$ sudo lshw -c network -businfo

I changed the Netplan configuration according to the test plan above, and
rebooted the system:
ubuntu@akis:~$ sudo netplan get
