This node is part of an A10-NSP development.
Carrier networks tend to stack three or more tags for internal purposes and therefore hiding the service tags deep inside of the stack. When decomposing such an access network frame, the processing order is typically reversed: First distinguish by service, than by other means.
This new netgragh node allows to bring the relevant VLAN in front (to the out-most position). This way other netgraph nodes (like ng_vlan) can operate on this specific type.
The example section of the man page contains two examples, how to use this node.
It also contains the sniffer insight of the manipulation process.

Just some style nits, some of which are applicable in places other than just where I left them. Functionally, it appears to be OK, but adding Julian while I'm still diving into netgraph for bluetooth bits.

| 225 | Spurious whitespace on blank lines in a couple spots | |
| 229 | The various case lines should line up with the switch | |
| 247 | Space between if and opening paren, error assignments should move to the next line | |

| 363 | We don't traditionally space assignments out like this, but I don't know that anyone's going to hassle over it. | |

| 474 | Operator belongs to the line before it, with the wrapping starting just after. | |
Run indent(1) on the source files.
Reduced comments from the boilerplate.
Changed hard coded ethertypes by global definitions introduced by D21846.
