Subject: vmd(8): allow locking a randomly assigned lladdr
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=6153f04ab7763e302a624f17fedf3295fd8117c8;p=openbsd

vmd(8): allow locking a randomly assigned lladdr

Provide a default value of a zero'd mac address so a user can still
specify the interface should be "locked" (only transmitting ethernet
packets with a matching source address). vmd will assign a random
address at vm launch.

As an example, this is now valid:

  vm "name" {
    interface {
      locked lladdr
    }
    ...
  }
