anymore.

Title:
  Wi-Fi interface "disabled by a hardware switch" if no *Ethernet* cable
  plugged in at boot -- Broadcom BCM4313 wl bcma brcmsmac; Realtek
  RTL8101E/RTL8102E r8169

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  
  I have set-up a bridge (br0) on eth0 of my laptop, as I'm using KVM from time to time.

  This is the content of /etc/network/interfaces:

  aaa@xxx:~$ cat /etc/network/interfaces 
  # This file describes the network interfaces available on your system
  # and how to activate them. For more information, see interfaces(5).

  # The loopback network interface
  auto lo
  iface lo inet loopback

  #
  auto eth0
  iface eth0 inet manual

  auto br0
  iface br0 inet dhcp
  	bridge_ports eth0
  	bridge_stp off
  	bridge_fd 0
  	bridge_maxwait 0

  My problem is, if I boot WITHOUT a live connection plugged into the
  ethernet port of my laptop, NetworkManager sees my WiFi as "disabled
  by a hardware switch".  As such, I can't use WiFi when there's no LAN.
  I can use WiFi when there's a LAN connection present, but it defeats
  the purpose of having a WiFi connection.
