support for mac address modification using dladm on links
There is currently no link property for mac address in dladm. vnic mac addresses can be set, but overall link mac addresses cannot. This feature exists in ifconfig, and in dladm for vnics, but should probably be extended to cover links as well as vnics.

As a workaround to this I create a vnic on the physical interface with the mac of my choosing. I have not noticed a performance impact doing this.
