Deja vu with https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=150249
The main symptom was lagg refusing to work in LACP mode.
In this case, the reason was that the driver didn't detect media properly, and
the "paperwork" with the kernel failed: the interface wasn't marked as full
duplex. As a result, LACP (which checks the full-duplex flag for the interface)
refused to use it. Remember that full-duplex is a prerequisite for LACP.
This seems to be a case of incomplete paperwork as well, although the necessary
bits seem to be in place.
In my case this was the problem with LACP (ieee8023ad_lacp.c):
---------
/*
* If the port is not an active full duplex Ethernet link then it can
* not be aggregated.
*/
if (IFM_TYPE(media) != IFM_ETHER || (media & IFM_FDX) == 0 ||
ifp->if_link_state != LINK_STATE_UP) {
lacp_port_disable(lp);
} else {
lacp_port_enable(lp);
}
---------
But according to ifconfig the interface is marked as full duplex and media
seems to be Ethernet. I would add some printf's here to check if this is really
the case and some other check is failing.
What does ifconfig -m say of the interfaces? But that lack of options looks
like a driver bug. And it would help to see its capabilities as reported by
ifconfig.
This is an example with an "em" interface.
