patch aonet.c to compile with -DVIMAGE, does not work!

When building the net/aoe kernel module, loading it into a kernel with VIMAGE
support results in the following dmesg error message:

link_elf_obj: symbol ifnet undefined
linker_load_file: Unsupported file type

Of course, kldload is not successful.

I then added to the Makefile of net/aoe (just as a quick try)

CFLAGS+= -DVIMAGE

and patched aoenet.c to make it compile again, see attachment. This gives the
following dmesg output when loading:

aoe: aoenet_init: ifp->if_input != ether_input
aoe: aoe_loader: AoE version 1.2.0 initialized

But after some minutes, the system crashes and reboots. So far, I was not able
to get a kernel error message. If anyone knows how to patch aoenet.c properly
to work with -DVIMAGE, this would help I guess. I'm just a FreeBSD beginner!

Thanks!

By the way: I'm doing this on a FreeNAS 9.2.1.8 machine (based on FreeBSD
9.2.1), since aoe would be nice there...
