make error after add 'device zyd' into MYKERNEL

[C Hwang]

Hi There, My first post!
I install a fresh 7.0 release a week ago. I get two wireless USB adapter
from Frys'. One is Linksys WUSB54GC which is working beautifully( I love
Linksys). The 2nd USB adapter is Trendnet TEW-424UB.  I want to add this
device into the kernel so I add a line in MYKERNEL(derive from
/usr/src/sys/i386/conf/GENERIC, make work with GENERIC)
device    zyd     #for Trendnet TEW-424U.

I also add  a line in  /usr/src/sys/conf/files (make can find the device
without complain)

dev/usb/if_zyd                  optional zyd

then do

#make buildkernel KERNCONF=MYKERNEL

The make process good all the way to if_rum.c but fail at if_zyd.c

there is a long error list but it seems all related to the same thing so I
will just list it what I think is enough.

printout of the make:

==================================================
I notice that there is an -o /usr/src/sys/dev/usb/if_zyd for compiler
option.  I don't know why it will use different compiler option for this
module.

I can do make at /usr/src/sys/modules/zyd and generate if_zyd.ko. I can
maually load it with kldload ./if_zyd.ko and see it with kldstat. It can not
be seen by ifconfig zyd0.

I have been spend about two day to mess around the if_zyd.c,
/usr/src/sys/NOTES,GENERIC.hint, /usr/src/sys/modules/Makefile,
/usr/src/sys/dev/usb/usbdevs

None change the result of make error.

Someone has experience on adding zyd into kernel with this make problem?

I read some other post it seems that there are more work need to be done but
I don't think it will make compile error like this.

Thanks,
