The current bcm43xx driver ignores any wireless-enable switches on mini-PCI and mini-PCI-E cards. This patch implements a new routine to interrogate the radio hardware enabled bit in the interface, logs the initial state and any changes in the switch (if debugging enabled), activates the LED to show the state, and changes the periodic work handler to provide 1 second response to switch changes and to account for changes in the periodic work specs.
