Redirecting traffic to a routing table based on specific bits in the UDP source port is not currently possible. Only exact match and range are currently supported by FIB rules. This patchset extends FIB rules to match on layer 4 ports with an optional mask. The mask is not supported when matching on a range. A future patchset will add support for matching on the DSCP field with an optional mask. Patches #1-#6 gradually extend FIB rules to match on layer 4 ports with an optional mask. Patches #7-#8 add test cases for FIB rule port matching. iproute2 support can be found here [1].
