RFC6241: Pipelining


RFC6241 has below information about Pipelining.

4.5. Pipelining

NETCONF requests MUST be processed serially by the managed
device. Additional requests MAY be sent before previous ones
have been completed. The managed device MUST send responses only in
the order the requests were received.

Does Confd handles the pipelining?
If Confd handles pipelining, how big is the queue size to hold client requests? Is the queue size configurable and what is the default queue size?
