[Qemu-devel] [PATCH 0/9] v2: Fixes, new way of discovering ports

[Amit Shah]

Hello,

These patches rework the way ports are announced to the guests. A
control message is used to let the guest know a new port is
added. Initial port discovery and port hot-plug work via this way now.

This was done to have the host and guest port numbering in sync to
avoid surprises after several hotplug/unplug operations and
migrations.

The ability to assign a particular port number to ports is also added
so that management software can control the placement of ports.

The other patches to handle scatter/gather for guest data and
migration fixes remain the same.

Please review.
