Thanks everybody. I understand the bottom line is I can't create a flow
to properly output to bonded ports.
What I am trying to achieve is to control distribution of DHCP traffic
on a bridge used by multiple untrusted VMs. I want DHCP broadcasts
delivered from VM to my local DHCP server VM and bonded ports. Before I
upgraded to bonded interfaces I was happily using output action to a
single interface. Now it obviously does not work. I tried to do output
to all enslaved interfaces of the bonded port, but it resulted in
traffic loop so I had to revert.
If anyone knows how to achieve this, I will be grateful for any ideas.
Regards,
Alex

I wonder the impact using the bundle, now that I have this in production =)
The bond is configured with SLB active-active (Yea, I know some of the
issues with this) but since, as you said, it bypasses the bond code this
should avoid the SLB problem, right ?
No it will actually exacerbate them. A lot of the "problems" of SLB
bonding are due to the SLB code trying to account for the fact that
the upstream switch is not aware it's participating in a bond. If
this compensation wasn't made, the behavior would be significantly
worse. The bundle action doesn't do any compensation at all. This can
cause severe problems leading to potentially black-holed traffic.
