net: bridge: vlan options: add support for tunnel mapping set/del
This patch adds support for manipulating vlan/tunnel mappings. The tunnel ids are globally unique and are one per-vlan. There were two trickier issues - first in order to support vlan ranges we have to compute the current tunnel id in the following way: - base tunnel id (attr) + current vlan id - starting vlan id This is in line how the old API does vlan/tunnel mapping with ranges. We already have the vlan range present, so it's redundant to add another attribute for the tunnel range end. It's simply base tunnel id + vlan range. And second to support removing mappings we need an out-of-band way to tell the option manipulating function because there are no special/reserved tunnel id values, so we use a vlan flag to denote the operation is tunnel mapping removal.
