Recently I came to know that,
Without any options fw classifier maps fwmark to classid.

tc filter add dev <iface> parent <qhandle> protocol ip prio 1 fw

i.e. if my packet has mark(0x10001) and class id is not set,
then above tc filter, will set class id = 0x10001 i.e. 1:1

But when I am trying it out, its not working!
I am having class 1:1 defined but its not at all hit.
