This method is called outside any transaction to attempt to
establish a port binding using this mechanism driver. Bindings
may be created at each of multiple levels of a hierarchical
network, and are established from the top level downward. At
each level, the mechanism driver determines whether it can
bind to any of the network segments in the
context.segments_to_bind property, based on the value of the
context.host property, any relevant port or network
attributes, and its own knowledge of the network topology. At
the top level, context.segments_to_bind contains the static
segments of the port's network. At each lower level of
binding, it contains static or dynamic segments supplied by
the driver that bound at the level above. If the driver is
able to complete the binding of the port to any segment in
context.segments_to_bind, it must call context.set_binding
with the binding details. If it can partially bind the port,
it must call context.continue_binding with the network
segments to be used to bind at the next lower level.
If the binding results are committed after bind_port returns,
they will be seen by all mechanism drivers as
update_port_precommit and update_port_postcommit calls. But if
some other thread or process concurrently binds or updates the
port, these binding results will not be committed, and
update_port_precommit and update_port_postcommit will not be
called on the mechanism drivers with these results. Because
binding results can be discarded rather than committed,
drivers should avoid making persistent state changes in
bind_port, or else must ensure that such state changes are
eventually cleaned up.
