I attach a patch that fixes some problems with divider reset and in
general simplifies the logic. Even with the patch, however, I still see
failures in my test case unfortunately. Probably there are rounding
errors

are fail to pass the 244us update cycle checking. Since we are in

So I think it should not be a bug.
Yes,

Just some further information concerning my earlier question
concerning vhost and virtio.
I'm using virtio to implement an emulated mac80211 device in the
guest. A simple network simulation will be used to control delivery of
frames between guests

Yes, that's fine. But I also see some cases in which the first upgrade
cycle after divider reset is not reported. The second, 1.5 seconds
after divider reset, is fine.
I think your patch can fix it. Right?
No. :( It makes it a lot less

Those patches make tcp migration use the help functions in
qemu-socket.c for support IPv6 migration.
Changes from v1:
- split different changes to small patches, it will be easier to review
- fixed some problem according to Kevin's comment
Changes from v2:
- fix issue of returning real error
-
Introduce set_socket_error() to set the errno, use
WSASetLastError() for win32.
Sometimes, clean work would rewrite errno in error path,
we can use this function to restore real errno.

Change inet_connect(const char *str, int socktype) to
inet_connect(const char *str, bool block),
socktype is unused, block is used to assign if set socket
to block/nonblock.
Retry to connect when -EINTR/-EWOULDBLOCK is got.
Connect's successful for nonblock socket when following
errors are got:
Use set_socket_error() to restore real erron,
set errno to EINVAL for parse error.

Use help functions in qemu-socket.c for tcp migration,
which already support ipv6 addresses.
For IPv6 brackets must be mandatory if you require a port.
Referencing to RFC5952, the recommended format is:
