Kubespray currently supports Linux distributions with Wireguard Kernel mode on Linux 5.6 and newer.
## Bandwidth Manager
Cilium’s bandwidth manager supports the kubernetes.io/egress-bandwidth Pod annotation.
Bandwidth enforcement currently does not work in combination with L7 Cilium Network Policies.
In case they select the Pod at egress, then the bandwidth enforcement will be disabled for those Pods.
Bandwidth Manager requires a v5.1.x or more recent Linux kernel.
For further information, make sure to check the official [Cilium documentation.](https://docs.cilium.io/en/v1.12/gettingstarted/bandwidth-manager/)
To use this function, set the following parameters
```yml
cilium_enable_bandwidth_manager: true
```
