Subject: [PATCH net-next 14/16] tipc: handle <0.0.0> as an alias for this node on outgoing msgs

From: Allan Stephens <allan.stephens@...driver.com>

Revises handling of send routines for payload messages to ensure that
they are processed properly even if the node's network address is
changed in mid-operation. The routines now treat the default node
address of <0.0.0> as an alias for "this node" when determining where
to send an outgoing message.
