- Subject: [PATCH] mesh: allow processing authentication frames in blocked state
- If authentication fails repeatedly e.g. because of a weak signal, the link
- can end up in blocked state. If one of the nodes tries to establish a link
- again before it is unblocked on the other side, it will block the link to
- that other side. The same happens on the other side when it unblocks the
- link. In that scenario, the link never recovers on its own.
- To fix this, allow restarting authentication even if the link is in blocked
- state, but don't initiate the attempt until the blocked period is over.
