Hi all!
That the second part of virtio-net backend transfer feature,
following previous
"[PATCH v9 0/7] net/tap: simple refactoring".
Here we realize postponing TAP opening to some future
point, when we know, are we going to do backend-transfer
incoming migration (and get open fd from migration stream),
or we should do open().
v9:
most of patches just picked from
"[PATCH v9 0/7] net/tap: simple refactoring".
but, 01 is new, and 09 is significantly changed:
instead of hacking with .check_peer_type and detecting
virtio-net by name, use the approach like in parallel
series for chardev:
"[PATCH v4 0/7] chardev: postpone connect":
introduce specific PROPERTY macro, and avoid connecting
in setter of "netdev" property.
Final part of virtio-net backend transfer is coming
soon and will be based on this series.

I will go through this but I'd like to see a test for this feature.
