After applying the update on my servers, I got massive problems in the
stability of my network connections. I was running bond in mode 6, which
now seems not to work anymore.

Maybe someone can check and confirm this behaviour. Unfortunately, all
of my servers are productive. I had to change them back to single NIC
operation to get them accessible again. I cannot do any further tests
with my environment.
