[PATCH phosphor-host-ipmid v2 2/4] ipmid: Remove assumptions about host IPMI sender objects

[OpenBMC Patches]

From: Jeremy Kerr <jk at ozlabs.org>

Currently, the IPMI daemon will only receive messages from a specific
(arbitrary) object path that the debug daemon used.

Instead, we should be listening to any signal that matches our interface
(org.openbmc.HostIpmi.ReceivedMessage). When replying to the message,
we should be using the signal sender info to properly address the
reply method.
