Wanted to update my findings on Buster with this patch. We use Mellanox
Connect-X5 series nic (dual port) and have a bonded setup.

Both ports are bonded with 802.3ad and the bond device is put on a
bridge (br0) and br0 gets the IP address.

In this setup with CONFIG_NET_SWITCHDEV enabled bond0 is not placed on
br0 and I see a message:

ifup: can't add bond0 to bridge br0: No data available

This happens with Mellanox inbox driver in Kernel but if I install
latest OFED there is no issue. So I'm not sure how other NIC's behave
with this option enabled.

Cheers,
