Subject: After Alpine upgrade from 3.12 to 3.20.2 facing issue with VXLAN and docker

Hello,

I recently did a Alpine upgrade from 3.12 to 3.20.2

My virtual machine has 2 interfaces i.e. eth0 & eth1
Both int's has public public IPv4 IP's from separate IP ranges and
separate gateways

eth0 is a primary int where I do SSH.
eth1 has static public IP which binds to my docker containers for
special connection via VXLAN.

After the upgrade, communication over eth1 is not working as expected.
I tried to use tcpdump to capture logs but nothing is there.
ovs-vsctl show command shows the correct IP and status of the interface.

I am kind of lost and not able to find the root cause for this issue
after the upgrade.

Any hints about the potential issue which is hindering the functionality?

Thanks & Regards,
Amey.

> special connection via VXLAN.

I am also creating a macvlan docker network and attaching it to eth1 int.
I am able to ping the destination systems from the base Alpine OS but
not from the Docker container.
