The following is a patch that adds support for vlan creation and
destruction within rcNG. Using the patch it's possible, for example,
to create a vlan, `vlan0' with the following directives in rc.conf:
vlan_interfaces="vlan0"
ifconfig_vlan0="DHCP"
ifconfig_vlan0_vlan_dev="xl0"
ifconfig_vlan0_vlan_tag="2"
Is this patch of general interest? Should I submit a PR?
The patch (also attached):
