9Abstract:
10
11 Encapsulation of the Self target to which FxRequest are sent to.
12 FxSelfTarget represents the client itself and is used to send IO to
13 itself.
14
15 Unlike the the local and remote targets, the IO sent to an Self IO
16 target is routed to the sender's own top level queues. A dedicated queue
17 may also be configured as the target for requests dispatched to the Self
18 Io targets.
