Subject: wpi port -- Intel PRO/Wireless 3945ABG chipset.
To: None <tech-kern@NetBSD.org>
From: Jean-Baptiste Campesato <camjelemon@gmail.com>

Hello,
I've just finished to port Damien Bergamini's wpi driver from OpenBSD.
The driver allows the use of the Intel PRO/Wireless 3945ABG chipset.
I've tested the WEP mode, but not the WPA mode.
The firmware can be downloaded here: http://bughost.org/ipw3945/ (Microcode)
Use "wpictl wpi0 -d WHEREISYOURWPI-ipw3945.ucode" to send the firmware
to the NIC and "wpictl wpi0 -k" to remove the firmware from the NIC.
Cordially,
Jean-Baptiste Campesato.
The modified files are: files.pci pcidevs pcidevs.h pcidevs_data.h in
src/sys/dev/pci and GENERIC in sys/arch/i386/conf
The added files are: if_wpi.c if_wpireg.h if_wpivar.h in src/sys/dev/pci
I also added the directory src/usr.sbin/wpictl/ with the files
Makefile and wpictl.c
The diff is for NetBSD-current
I haven't written the mans yet.
