Is vni100 the vxlan interface or the bridge interface?

vni100 should be the bridge slave here.
So those options could be in the same level of "allowed-vlan" and "native-vlan"

@c-po It seems you only implement the "type bridge_slave neigh_suppress on"
And "type bridge_slave learning on" is not implemented in this PR.
Will you add this also?
Thank you
