macvlan_config on linux 2.6.16 build problem.

I'm trying to compile vconfig (vlan.1.9.tar.gz) for 2.6.16 linux kernel.

The problem is:
Making vconfig.c
gcc        -g -D_GNU_SOURCE -Wall -I/usr/src/linux/include -c vconfig.c
gcc        -g -D_GNU_SOURCE -Wall -I/usr/src/linux/include  -o vconfig
vconfig.o
strip vconfig
gcc        -g -D_GNU_SOURCE -Wall -I/usr/src/linux/include  -o

I've look on changes between candela_2.6.11.patch and
candela_2.6.13.patch - API changed a little. 
macvlan_ioctl.ifname is now array instead of pointer. While I could add
strcmp here and there in the sources, I'm not sure about that API calls like
MACVLAN_UNBIND. They are uncommented for some reason I thinkg, but I'm kind of
guest in vconfig world. I can't use candela_2.6.11.patch with 2.6.16
kernel too.

Please - if you could give me some info about what I should do with this
problem I would be very thankful.
