Subject: [PATCH] [PATCH] rt2x00: Store "STARTED" state during suspend
Store the started state into a new flag DEVICE_STARTED_SUSPEND
and set this when suspending while the device was started.
We can't check for is_interface_present() since only mac80211
knows if there are monitor interfaces present.
