- Value 0 means unlimited. The actual number of supported - VLAN headers is the smallest of vlan-limit, the number - of VLANs supported by Open vSwitch userspace (currently 2), and the - number supported by the datapath. + Open vSwitch userspace currently supports at most 2 VLANs, and each + datapath has its own limit. If vlan-limit is nonzero, + it acts as a further limit.
