Title:
  Ubuntu 16.04 - Broadcom Corporation BCM43602

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On startup it shows some strange errors on dmesg:
  Bluetooth: hci0: BCM20703A1
  Bluetooth: hci0: BCM (001.001.005) build 0000
  IPv6: ADDRCONF(NETDEV_UP): wlp2s0: link is not ready
  brcmf_add_if: ERROR: netdev:wlp2s0 already exists
  brcmf_add_if: ignore IF event
  IPv6: ADDRCONF(NETDEV_UP): wlp2s0: link is not ready
  brcmf_add_if: ERROR: netdev:wlp2s0 already exists

  Looks similar to bug in Ubuntu 15.04

  Also from time to time the wifi icon disappears and it appears a
  cabled icon (after suspend and resume in my case)

  My laptop is a Dell XPS 15 9550
