Previously I didn't mention that there are some functions missing from

the FreeBSD's NDIS api. These are:



NdisIMCopySendPerPacketInfo

strncat

KeQuerySystemTime

KeBugCheckEx

KeTickCount



With the help of NDIS reference and Linux ndiswrapper I have been able

to implement all but KeBugCheckEx (they are all rather simple but I

can't be 100% sure they're correct and exported appropriately).



Now I'm able to load the driver and don't get any of the "ntoskrnl dummy

called..." messages which probably means that there are no missing

functions the driver tries to call.



Unfortunately I'm still left with the:

ndis0: NDIS ERROR: 40001b7c (unknown error)

error message and the device doesn't work.



ifconfig ndis0 shows:



ndis0: flags=8806<BROADCAST,DEBUG,SIMPLEX,MULTICAST> mtu 1500

         ether 00:13:e8:64:aa:f7

         media: IEEE 802.11 Wireless Ethernet autoselect

         status: no carrier

         ssid "" channel 1

         authmode OPEN privacy OFF txpowmax 100 bmiss 7 protmode CTS



The LED indicating whether WLAN is on doesn't light up. Calling ifconfig

ndis0 up results with the following kernel messages:



ndis0: NDIS ERROR: 40001b7c (unknown error)

ndis0: NDIS NUMERRORS: 2

ndis0: argptr: 0x56524457

ndis0: argptr: 0xdd



And that's all I have been able to achieve so far :)



I'll try to read some more of NDIS specification, locate the source of

the aforementioned error message and generally try to blindly find

something.



Maybe someone has some suggestions? Maybe I should also try to post my

questions to some other list?



The diff of my changes: http://marcin.studio4plus.com/ndis/ndis.diff

All changes are confined to the /usr/src/sys/compat/ndis directory. The

functions I have added are implemented in a quick and dirty way :)

Check it, it may work for you with ndis.
