Hi, Welcome Red Techie.
I am patient zero on this even.
Yes putting the mac acl will work on the port, but that will kill the purpose of the packet, which is quick notify to other AP's.
The problem is the STP leak of this packet on the LAGS.
Pick one of the lags that create your circular network and add it there. That prevents the reflection in the network while allowing the packet to get out and be used.
Netgear ... Whats the update to this issue? When can we expect a FW fix? I suspect you will be getting more users figuring out this is a problem.

I have a few LAGs and the native stacking functioanlity of the GS752TXS's enabled. See Image.
Do I need to add it to all of them (including the stacked links)?
Also the "quick notify" is that the zero-handoff config? As I am not using that:
Or is quick notify something completely different with the UBNT hardware?
We have the same issue.
Our Netgear switch setup looks like this:
- Level One: Switch Stack of 2 x NetGear GS752TS Switches
- Level Two: Switch Stack of 5 x NetGear GS752TS Switches
These stacks are connected via a 6 port LAG. Could we please add the GS752TS to the list of switches needing a FW fix for this issue.
