I've been playing with it and actually am able to get it working. Enabling RNDIS
support is a bit different than in other devices, though. The Droid (probably
other
eclair devices as well) uses USB gadget support where as older versions of
android
use USB function support. But because of some technicalities, it's no longer
possible
to use USB mass storage or adb (over usb). I'm sure there's a way to get both to
work, though.

@GadgetMG
Can you please provide steps on how you got RNDIS patched on the Droid? Could
you
also please elaborate the USB gadget more?

Well, the kernel needs completely recompiled. The kernel source can be checked
out
from android.git.kernel.org. You also have to check out a prebuilt toolchain. I
just
downloaded the entire android source with repo, but that took a while. To
compile,
you just have to set CROSS_COMPILE to your toolchain location, and ARCH to arm.
I did
a make sholes_defconfig to load the default configuration for the Droid, and
then I
added Netfilter support and changed the USB gadget driver with make menuconfig.
Also,
I had to comment out both instances of android_usb_set_connected in
arch/arm/mach-omap2/board-sholes.c because the Android gadget driver provides
that
function. It's a pretty bad way of going about it. Hopefully somebody will come
along
who could modify the existing Android gadget driver to include RNDIS.

Ok, I am going to try and re-create what you did, but I have several questions.
-Can you elaborate on where you got the default configuration for the Droid?
How do
you know what the default configuration for the Droid is sholes_defconfig?
-Specifically what did you change about the USB gadget driver? Only RNDIS?
-Why did you add Netfilter support? Is it also needed for android-wired-tether?
-Does commenting out android_usb_set_connected remove any functionality (sdcard
mounting, adb, etc.)?
-Finally, how did you update the kernel on the phone? Adb? Nandroid?
Thanks.

A lot of kernel patching has been tossed around on issue 205 of
android-wifi-tether.
I just switched the default USB gadget driver from the Android driver to the
Ethernet
driver. Netfilter support is needed because it does the routing. Changing the
driver
has side effects, though. USB mass storage and adb NO LONGER WORK (except in
recovery
mode.) A much better alternative would be to patch the original Android driver
to
include USB networking, but I'm not able to do that. In order to flash the
kernel,
you have to take zImage from arch/arm/boot/zImage and use the spboot tool to
make it
work (http://www.sholes.info/hg.) Then you take the resulting boot.img file and
flash
it through adb in recovery mode (flash_image boot boot.img.) Oh, and the wifi
driver
has to be recompiled, too. That can be checked out from android.git.kernel.org
as
well. You have to define ARCH as zoom2 and KERNEL_DIR to the path of the kernel
source. Also, the toolchain bin folder has to be added to your PATH. It's pretty
complicated, but it does work. Make sure you make a nandroid backup, though.

Okay, I've been working and have actually been able to hack up a partially
working
android.c. That means that you don't have to switch the driver or comment out
anything in sholes.c. All that has to be done to make it work is patch
android.c and
add Netfilter support in the config. Currently, ADB doesn't work, but mass
storage
still does. The ethernet driver doesn't have RNDIS, either, but I'll get to that
eventually. It works on Linux, at least. It probably won't work on Windows,
because
Microsoft only plays nice with RNDIS.
Attached is the patch and my config.

Is there any update for the new kernel pushed to the Droid (2.1)?

No. The latest kernel is still 2.6.29. Only of couple minor changes have been
made.

See this thread for patches that update the Android gadget to the one included
with
2.6.32.
