I think it could work.But if I do match on IPv6 Flowlabel ,I think it should be :
tc filter add dev eth0 parent 1:0 protocol ipv6 prio 1 u32 \
match u32 0x0 0x000fffff at 0 classid 1:1
for the IPv6 header's first 4 bits is the Version field and following 8 bit is the TC
field.
What is tcng? I haven't heard about it.
