+/* 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+ *  - other GPL, unpublished (until now), Linux driver code,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.
