These changes allow vlans to be layered above agr, with the attach and detach propogated to the member ports in the aggregation. Note the agr interface must be up before the vlan is attached. Adds SIOCINITIFADDR support to the wm driver for setting the AF_LINK address, necessary for agr to be able to set the mac addresses of each port to the agr address (i.e. so it can receive all intended traffic at the hardware level). Adds support for disabling the LACP protocol by setting LINK1 on the agr interface (e.g. ifconfig agr0 link1). In consultation with tls@.
