Parts of this driver are based on the GPL part of the official

Realtek driver.

Parts of this driver are based on the rtl8180 driver skeleton

from Patric Schenke & Andres Salomon.

Parts of this driver are based on the Intel Pro Wireless 2100 GPL driver.

Parts of BB/RF code are derived from David Young rtl8180 netbsd driver.

RSSI calc function from 'The Deuce'

Some ideas borrowed from the 8139too.c driver included in linux kernel.

|
|
We (I?) want to thanks the Authors of those projecs and also the
|
|
Ndiswrapper's project Authors.
|
|
|
|
A big big thanks goes also to Realtek corp. for their help in my attempt to
|
|
add RTL8185 and RTL8225 support, and to David Young also.
