This module provides a convenient wrapper around both CMD_[CANCEL_]_REMAIN_ON_CHANNEL APIs. Certain protocols require going offchannel to send frames, and/or wait for a response. The frame-xchg module somewhat does this but has some limitations. For example you cannot just go offchannel; an initial frame must be sent out to start the procedure. In addition frame-xchg does not work for broadcasts since it expects an ACK. This module is much simpler and only handles going offchannel for a duration. During this time frames may be sent or received. After the duration the caller will get a callback and any included error if there was one. Any offchannel request can be cancelled prior to the duration expriring if the offchannel work has finished early.
