svn commit: r328922 - head/sys/dev/etherswitch

New Revision: 328922
URL: https://svnweb.freebsd.org/changeset/base/328922

Log:
  [etherswitch] add initial support for potentially configuring and fetching the switch MAC address.
  
  Switches that originate their own frames (eg obvious ones like Pause frames)
  need a MAC address to use to send those frames from.
  
  This API will hopefully begin to allow that to be configurable.
