	---help---

	  Say Y if you intend to use Qualcomm IPC router protocol.  The

	  protocol is used to communicate with services provided by other

	  hardware blocks in the system.



	  In order to do service lookups, a userspace daemon is required to

	  maintain a service listing.

	---help---

	  Say Y here to support SMD based ipcrouter channels.  SMD is the

	  most common transport for IPC Router.
