Netlink error after upgrade to 0.10.0

[TokuiNico]

Hi, I upgrade defguard core (0.10.0) and gateway (0.6.2) to latest version.

I got the error message in gateway service

Apr 12 01:04:03 ip-10-0-249-237 docker[22471]: [2024-04-11T17:04:03Z ERROR defguard_gateway::gateway] Interface configuration failed: WireGuard error Netlink error: Serialized netlink packet (13724 bytes) larger than maximum size 12288

and got another error message in core service

I try to downgrade to old version but meet migration error.

It seems that the defguard-gateway service failed to load the config after restarting due to too many devices. The error message indicates that a serialized netlink packet of 13724 bytes is larger than the maximum size of 12288 bytes.

I successfully started the service by removing some devices so that the config file was smaller than the maximum size. However, I also need to reconfigure the removed devices...

I think the problem could be hear Have any reason to set the max buffer length as 12288 ? I didn't see any constraint like this in the Golang implemention.
