Bug description:
  It has recently come to our attention that some laptops, in particular
  the lenovo b470 machines, have only one antenna. Unfortunately, they
  have decided to attach the auxilary antenna in the factory and not the
  main antenna. Udev sounds like the right place to quirk for this.

  Presently we're using an upstart job, the text of which is :

  # LenovoBx70eAtherosAntenna.conf
  #
  # Lenovo B[45]70e systems with Atheros AR9285 wifi only have one
  # antenna, but the ath9k driver defaults to using two antennas (Main
  # for Tx, Aux for Rx).  This job reconfigures the driver to use the
  # main antenna for both Tx and Rx before networking starts.

  description     "Fix antenna configuration for Atheros wifi on
  b470e/b570e"

  start on starting networking

  task

  script
          # only required for Lenovo B470e and B570e
          dmidecode --string system-version | grep --quiet --line-regex "Lenovo B[45]70e" || exit 0
          
          # only required for Atheros AR9285 devices
          lspci -n | grep --quiet --extended-regexp "^[0-9a-f:.]* 0280: 168c:002b" || exit 0

          # configure the device to use antenna 1 (Main) for both tx and rx
  	iw phy0 set antenna 1 1 
  end script
