The can_dlc value that is passed to the kernel is not sanitized in cangw
therefore we only update the help text and some comments in gw.h.
In the case that the CAN interface supports len8_dlc by setting
CAN_CTRLMODE_CC_LEN8_DLC the can-gw module can modify the full DLC value
range (0 .. 15) for Classic CAN frames.

Similar to referencing iptables rules by their line number this UID allows to
reference created routing jobs, e.g. to alter configured data modifications.
The UID is an optional non-zero value which can be provided at routing job
creation time. When the UID is set the UID replaces the data modification
configuration as job identification attribute e.g. at job removal time.
The UID option is provided by mainline Linux 4.2+

This comment was added to the kernel in patch:
391ac12 can: gw: add a per rule limitation of frame hops
The corresponding can-utils commit is:
ad7f44095a (cangw: add an option for the per rule limitation of frame hops)
which somehow introduced the difference even though it referenced commit
391ac12.

This patch fixes paths mentioned in the files which are wrong now, due the move
of the files in the previous patch.

This makes it possible to import header from the kernel more easily, e.g.:
cd $path_to_linux_repo
make headers_install
rsync -a --exclude .\* usr/include/linux/can* $path_to_can_utils/include/linux
[mkl: also move isotp.h although Uwe skipped it as it is not
part of the upstream kernel; adapt commit log accordingly]
