            Bug ID: 26364
           Summary: Add "rollback" to RTCSdpType
           Product: WebRTC Working Group
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebRTC API
          Assignee: public-webrtc@w3.org
          Reporter: kiran.guduru@samsung.com
                CC: public-webrtc@w3.org

Section 4.1.4.2 of JSEP draft is explaining the "rollback" is a special session
description type used to rollback the sessions.

But RTCSdpType of WebRTC draft is missing this SDP type.
It is better to add this type to RTCSdpType and explain the same in
setLocalDescription/setRemodeDescription, like

. If setLocalDescription/setRemoteDescription is received with RTCSdpType
"rollback".
. If the state is stable, return with invalid state exception and abort the
following steps.
. Consider the sdp string to be empty string (clamping the string to be empty
to avoid exception cases) and rollback the state from current unstable  state
to previous stable state.
