No module parameters please. If you need to set something do it using
rtnl_link_ops. Thanks.
I understand what you ask for, but without module parameters userspace
don't work. During boot (dracut) the virtio netdev gets enslaved
earlier than when userspace comes up, so failover has to determine the
setting during initialization/creation. This config is not dynamic, at
least for the life cycle of a particular failover link it shouldn't be
changed. Without module parameter, how does the userspace specify this
value during kernel initialization?
Can we enable this by default and not make it configurable via module
parameter?
Is there any usecase where someone expects rename to fail with failover
slaves?
