Kernel 2.6.26, iproute2 latest release. All required modules is loaded.
What did i miss or doing wrong?

tc filter add dev ifb0 protocol all basic match "meta(rt_iif eq tap0)" classid 1:100 

tc -s -d filter show dev ifb0
filter parent 1: protocol all pref 49152 basic
filter parent 1: protocol all pref 49152 basic handle 0x1 flowid 1:100
  meta(-1 eq -1)

Whatever i try - it doesn't work
./tc filter add dev ifb0 protocol all basic match meta \(rt_iif eq tap0\) classid 1:100

But if i do
tc filter add dev ifb0 protocol all basic match u32\(u32 0x01020300 0xFFFFFF00 at 12\) classid 1:100

i will get everything "right"

filter parent 1: protocol all pref 49151 basic
filter parent 1: protocol all pref 49151 basic handle 0x1 flowid 1:100
  u32(01020300/ffffff00 at 12)

Sure i will try to debug and find bug by myself, but i am not sure i can do that :-)
