It should work. You just have to be aware that your kernel
is doing some odd things ...

Only if you try to change the DS field.

No. tc_index does not have to equal the DSCP or DS field.
In dsmark, tc_index is an index to a table with DS field
changes. All you need to do is to reserve a tc_index value
for non-IP traffic, and only mark IP traffic with other
values than that.
