From: Vlad Yasevich <vladislav.yasevich@xxxxxx>
When processing an ACK for ADD_IP parameter, we only release
the routes on non-active transports. This can cause a wrong
source address to be used. We can release the routes and
cause new route lookups and source address selection so that
new addresses can be used as source. Additionally, we don't need
to lookup routes for all transports at the same time. We can let
the transmit code path update the cached route when the transport
actually sends something.
