Staging: wlags49_h2: add Agere driver for HERMES II and HERMES II.5 chipsets

WLAN driver for cards using the HERMES II and HERMES II.5 chipset

Based on Agere Systems Linux LKM Wireless Driver Source Code,
Version 7.22; complies with Open Source BSD License.

The software is a modified version of wl_lkm_722_abg.tar.gz from the
Agere Systems website, addapted for Ubuntu 9.04 and modified to
fit in the current Linux kernel (2.6.31).

Modified for kernel 2.6 by Henk de Groot <pe1dnn@amsat.org>
Based on 7.18 version by Andrey Borzenkov <arvidjaar@mail.ru> $Revision: 39 $
