a dummy bridge for Xen domUs in my case).

22.04:
- linux-image-5.15.0-57-generic
18.04:
- linux-image-4.15.0-201-generic
-> broken:

Title:
Network bridge issue after updating kernel to 5.4.0-137
Status in linux-meta package in Ubuntu:
Confirmed
Bug description:
Hello,
After updating the kernel from 5.4.0-136 to 5.4.0-137 network bridge are not
working any more.
I can see the bridge with "ip add show" or "brctl show". Network is up and I
can reach the full network from the host through the bridge.
VM on the host can not reach network or host and host can not reach
the VM through the bridge.
We have bonded interface used in the bridge and one bridge without IP
and one with an IP. DHCP is off on booth bridge.
Downgrading the kernel to 5.4.136 (Ubuntu 5.4.0-136.153-generic
5.4.218) seem to work fine.
Thank you for your help.
