[Bridge] [BUG/PATCH/RFC] bridge: locally generated broadcast traffic may block sender
...behalf of the socket openened by nc.
It will be sent as soon as the link goes up again, and the application
will promptly unblock and finish.
The tx_queue indication for the sending socket is the clue.
The packets (or rather sk_buffs) generated through the socket are accredited
to the socket's wmem_alloc memory quota. Because one link is down,
sk_buffs will be queued on the transmit queue of one interface.
While they are queued, they won't be freed, causing the socket to run out
of its wmem_alloc quota, because they are still associated to the socket.
Why the first bridge interface only?
