Hello Kurt,

i applied all your patches for the can-utils and the network layer stuff to
the BerliOS SVN in socketcan/branches/j1939 for testing.

Besides some minor adaptions to support the SVN i left out some infrastructure
changes you made in patch 2/5 to constify this ...

> +static const struct can_proto *proto_tab[CAN_NPROTO] __read_mostly;

and this ...

(..)

These infrastructure changes did not really belong to the rtnetlink support.

The can-j1939.ko builds properly in the SVN against 2.6.39-rc5 and the
net-next-2.6 tree - and e.g. against a debian wheezy kernel:

make KERNELDIR=/usr/src/linux-headers-2.6.38-2-686-bigmem

As it is pretty easy now to build the kernel modules & your provided can-utils
we hopefully get some more feedback from j1939 users.

Best regards,
Oliver
