By the way, you can attach fw_mark classifier WITHOUT specifying
any marks and then it will try to directly map mark to class numbers.
You can then specify class numbers directly in ip{chains,tables} ;)

I saw this discussed here on the list before and when I tried to find
more details I came up dry -- do you happen to remember/know the mapping?

I found it in sources. When fwmark has no subfilters
then maps fwmark directly into classid.
So that 0x0002010 is classid 2:10
