Checking for a set bit outside a "mask" value can be easily done with "binary" operations; unfortunately, awk doesn't allow for this, afaik. bash can do it:
You see that bit0 is NOT in MASK, but bit7 is.

Traffic control index filter(8) Linux Traffic control index filter(8)NAME
tcindex - traffic control index filter
SYNOPSIS
tc filter ... tcindex [ hash SIZE ] [ mask MASK ] [ shift SHIFT ] [ pass_on | fall_through ] [ classid CLASSID ] [ action ACTION_SPEC ]
DESCRIPTION
This filter allows to match packets based on their tcindex field value, i.e. the combination of the DSCP and ECN fields as present in IPv4
and IPv6 headers.
OPTIONS
action ACTION_SPEC
Apply an action from the generic actions framework on matching packets.
classid CLASSID
Push matching packets into the class identified by CLASSID.
hash SIZE
Hash table size in entries to use. Defaults to 64.
mask MASK
An optional bitmask to binary AND to the packet's tcindex field before use.
shift SHIFT
The number of bits to right-shift a packet's tcindex value before use. If a mask has been set, masking is done before shifting.
pass_on
If this flag is set, failure to find a class for the resulting ID will make the filter fail and lead to the next filter being con-
sulted.
fall_through
This is the opposite of pass_on and the default. The filter will classify the packet even if there is no class present for the
resulting class ID.
