Subject: [PATCH 04/57] port: Don't renew raw transport.
|
|
|
|
Renewing of the transport on announce/sync timeout is needed in the
|
|
client-only mode to avoid getting stuck with a broken multicast socket
|
|
when the link goes down.
|
|
|
|
This shouldn't be necessary with the raw transport. Closing and binding
|
|
of raw sockets can apparently be so slow that it triggers a false
|
|
positive in the clock check.
