macvlan support

[jslay88]

Is your feature request related to a problem? Please describe.
I am trying to setup Multus CNI, but it requires macvlan. I would like to have macvlan added, or know how to add it myself.

Describe the solution you'd like
Ability to bridge host network adapter to pod for mDNS/broadcast. This is usually done via macvlan.

Describe alternatives you've considered
Not sure of any other alternatives for bridging host adapter within kubernetes for mDNS/broadcast beyond macvlan.

Additional context
I have a service that needs to be able to attach to the same subnet as the host itself, and be able to utilize mDNS/broadcast for avahi services.

Same here. Did you find any alternatives?

I left k3os due to it being abandoned. K3s or k0s on something like Debian or Arch should work, as there is macvlan support.
