* Radio tuning for GCT GRF5101 on RTL8180

* Copyright 2007 Andrea Merello <andreamrl@tiscali.it>

|

* Modified slightly for gPXE, June 2009 by Joshua Oreman.
|
||||
*
|
||||
* Code from the BSD driver and the rtl8181 project have been
|
||||
* very useful to understand certain things
|
||||
*
|
||||
* I want to thanks the Authors of such projects and the Ndiswrapper
|
||||
* project Authors.
|
||||
*
|
||||
* A special Big Thanks also is for all people who donated me cards,
|
||||
* making possible the creation of the original rtl8180 driver
|
||||
* from which this code is derived!
