Re: [Xen-devel] [PATCH v4 06/13] xen/pvcalls: implement bind command

Send PVCALLS_BIND to the backend. Introduce a new structure, part of
struct sock_mapping, to store information specific to passive sockets.
Introduce a status field to keep track of the status of the passive
socket.

This queue is not introduced until patch 8.
