David Cermak 898cac0061 modbus: Exit server task gracefully to correctly cleanup lwip internals ... Current lwip implementation does not support deleting a task which is actively waiting on `select()` or `poll()` API. Therefore we have to make sure that `select()` exits to deallocate its internal callback before deleting the task. This is achieved by a shutdown semaphore which informs the client once the `select()` exitted. fix slave		2021-02-10 13:12:54 +00:00
