Here it asked me politely what to do:
I dont have share/man/man4/man4.i386/ndis.4
but I have share/man/man4/ndis.4

Here I get:
link_elf: symbol M_USBDEV undefined

and kernel will not load it.
I have custom kernel without usb stuff (it is loaded via module)
The only place where M_USBDEV is defined is in sys/dev/usb/usb.h
and I'm somehow at dead end.

I can load new if_ndis.ko with old ndis.ko but that is not usefull.
