-/* Linux device driver for RTL8180 / RTL8185 / RTL8187SE
- *
- * Copyright 2007 Michael Wu <flamingice@sourmilk.net>
- * Copyright 2007,2014 Andrea Merello <andrea.merello@gmail.com>
- *
- * Based on the r8180 driver, which is:
- * Copyright 2004-2005 Andrea Merello <andrea.merello@gmail.com>, et al.
- *
- * Thanks to Realtek for their support!
- *
- ************************************************************************
- *
- * The driver was extended to the RTL8187SE in 2014 by
- * Andrea Merello <andrea.merello@gmail.com>
- *
- * based also on:
- *  - portions of rtl8187se Linux staging driver, Copyright Realtek corp.
- *    (available in drivers/staging/rtl8187se directory of Linux 3.14)
- *  - other GPL, unpublished (until now), Linux driver code,
- *    Copyright Larry Finger <Larry.Finger@lwfinger.net>
- *
- * A huge thanks goes to Sara V. Nari who forgives me when I'm
- * sitting in front of my laptop at evening, week-end, night...
- *
- * A special thanks goes to Antonio Cuni, who helped me with
- * some python userspace stuff I used to debug RTL8187SE code, and who
- * bought a laptop with an unsupported Wi-Fi card some years ago...
- *
- * Thanks to Larry Finger for writing some code for rtl8187se and for
- * his suggestions.
- *
- * Thanks to Dan Carpenter for reviewing my initial patch and for his
- * suggestions.
- *
- * Thanks to Bernhard Schiffner for his help in testing and for his
- * suggestions.

- *   by itself.
- *
- * - I could route MGMT frames (currently sent over VO queue) to the MGMT
- *   queue but since mac80211 will do not know about it, I will probably gain
- *   some HW priority whenever the VO queue is not empty, but this gain is
- *   limited by the fact that I had to stop the mac80211 queue whenever one of
- *   the VO or MGMT queues is full, stopping also submitting of MGMT frame
