Hi

I assume you're trying to match the tos field.  u32 uses strtol
to read numeric values. Values prefixed with a 0 are assumed to
be octal you have to write 0x0011... and 0x00ff.... in order
to have it interpreted in hex.

Try this:

tc filter add dev imq parent 10:0 protocol ip \
  prio 1 u32 match ip tos 0x10 0xff flowid 1:10
