I am not quite sure what the point is of this patch. What do you need to recover from?

To avoid possible loss of notification, the PW message handler scans the route
back from the source device to identify end of the broken link.

Do you mean if port-writes are dropped? Then they did not reach you in the first place. If a link in between is broken, the associated switch will 'complain' and send port-writes, no?
