Implementation detail: we will need to support sending a synthetic actor system ID when LACP links are spread across multiple faucet datapaths (at the moment we use dp_mac which is different per datapath).
This works now, if you set the lacp
id to the same on multiple switches it will act as a single lacp bundle.
Note: currently if you override dp_mac
and set your own custom mac addresses per switch then this could break our current mclag implementation. If anyone actually wants to do this let me know and we'll open a new ticket to fix that behaviour.
Commonly referred to by the term MC-LAG or MLAG, the ability to split LACP bundles across multiple distinct switches in the same faucet stack would be a very useful feature.
