NDISulator with Intel 2200 b/g on 5.2.1-RELEASE-p9 (some success ...almost working)

[Joey Mingrone]

Hi all,

Here are the steps I took:

I built a new kernel with "options KSTACK_PAGES=8" to accommodate the large 
alloc the w22n51.sys driver makes on the kernel stack

I added the following directories from CURRENT under my source tree:
src/sys/compat/ndis 
sys/modules/ndis
sys/modules/if_ndis 
src/sys/dev/if_ndis 
src/usr.sbin/ndiscvt

In /sys/compat/ndis/subr_ntoskrnl.c I had to comment out the following lines 
to get everything to build:
#include <sys/kdb.h>
kdb_enter("ntoskrnl_debugger(): breakpoint");

cd /usr/src/usr.sbin/ndiscvt
make
make install

cd /sys/modules/ndis
make
make install

I put w22n51.sys and w22n51.INF in /sys/modules/if_ndis.  
If anyone is looking for these file they can be found inside this zip: 
http://www.powernotebooks.com/Support/intel_2200_wlan.zip

cd /sys/modules/if_ndis
ndiscvt -i w22n51.INF -s w22n51.sys -o ndis_driver_data.h
make

I got an an error: "make: don't know how to make pccarddevs.h. Stop", so I  
removed pccarddevs.h from /sys/modules/if_ndis/Makefile an it built okay.

make install

kldload -v ndis -> Loaded ndis, id=3
kldload -v if_ndis -> worked sometimes, other times the command would just 
hang, but the system would still be usable

when kldload if_ndis did work, the output would look like:
ndis0: <Intel(R) PRO/Wireless 2200BG Network Connection> mem 
0xff9ee000-0xff9eef
ff irq 11 at device 2.0 on pci2
ndis0: NDIS API version: 5.1
ndis0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 5.5Mbps 11Mbps
ndis0: 11g rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
Loaded if_ndis, id=7

Then ifconfig -a would show:

bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
        inet6 fe80::20e:a6ff:fec4:a0b1%bge0 prefixlen 64 scopeid 0x1
        inet 192.168.0.4 netmask 0xffffff00 broadcast 192.168.0.255
        ether 00:0e:a6:c4:a0:b1
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
plip0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet 127.0.0.1 netmask 0xff000000
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
ndis0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        ether 00:0e:35:1f:df:57
        media: IEEE 802.11 Wireless Ethernet autoselect
        status: no carrier
        ssid ""
        channel -1 authmode OPEN powersavemode OFF powersavesleep 100
        wepmode OFF weptxkey 1

Next I did: 

wicontrol -i ndis0 -l 
output: 0 stations:

ifconfig ndis0 inet 192.168.0.5 netmask 255.255.255.0 ssid 5270-4

Sometimes this would output: 
ifconfig: ioctl (SIOCAIFADDR): File exists

Other times it would work.  I think doing "ifconfig bge0 down" first helped.

now the output from "ifconfig -a" looked like:

bge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
        inet6 fe80::20e:a6ff:fec4:a0b1%bge0 prefixlen 64 scopeid 0x1
        inet 192.168.0.4 netmask 0xffffff00 broadcast 192.168.0.255
        ether 00:0e:a6:c4:a0:b1
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active

        inet 127.0.0.1 netmask 0xff000000
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
ndis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet6 fe80::20e:35ff:fe1f:df57%ndis0 prefixlen 64 duplicated scopeid 
0x4
        inet 192.168.0.5 netmask 0xffffff00 broadcast 192.168.0.255
        ether 00:0e:35:1f:df:57
        media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/54Mbps)
        status: associated
        ssid 5270-4 1:5270-4
        channel 6 authmode OPEN powersavemode OFF powersavesleep 100
        wepmode OFF weptxkey 1

wicontrol -i ndis0 -l:
1 station:
ap[0]:
        netname (SSID):                 [ 5270-4 ]
        BSSID:                          [ 00:0f:66:36:cb:e8 ]
        Channel:                        [ 6 ]
        Quality/Signal/Noise [signal]:  [ 115 / 115 / 0 ]
                                [dBm]:  [ 115 / -34 / -149 ]
        BSS Beacon Interval [msec]:     [ 0 ]
        Capinfo:                        [ ]

Now I unplugged bge0 and successfully pinged 192.168.0.x addresses on the 
local LAN using the ndis0.

So that's what successfully worked.  Here's are some of the problems:

Even with a defaultrouter entry in rc.conf, nothing outside the local LAN 
could be reached.

Trying to loading the two ndis kernel modules from /boot/loader.conf wouldn't 
allow the system to boot.

I hope that all makes sense.
