You mean, for agr+bridge ?
I suspect link1 is causing the issue you're seeing: without any LACP
negotiation, a packet going out by wm0 will be received on wm1, and

Why?  wm0 and wm1 aren't in the bridge, and if you have LACP turned off
entirely, the host on the other end must be configured so it doesn't
reflect packets this way, either.

But in his setup, if I understood it properly, the other end is a switch,
which probably can't deal gracefully with this setup.

It is indeed a switch without support for LACP. The manpage does say link1 disables LACP.

Note that the network works fine on the dom0 using agr0, it's only when agr0 is on a bridge that problems appear (and even then the host's networking, running with agr0 as the primary interface, still works). I mention this because if the issue was just LACP, I can't see why the dom0 networking would work as expected.

So perhaps there is a unhandled situation somewhere? For instance, would agr(4) without link1 and bridge(4) work together?
