Re: lag.
LACP doesn't even work between wifi and ethernet, doesn't it? I thought it required configurations on the network switch, which implies ethernet.
The bug they mention seems to only apply to the LACP mode of link aggregation, when they should probably be trying to use failover from this page. Where what you do is set the ethernet as the primary and the wifi as the failover (although this doesn't seem to work on their case because the ethernet interface is dynamically created.
Other complaints and issues they have still apply as well.
