Hi,
this short series allows the tc tool to configure masked matches on the
ICMP code and type. Unmasked matches are already supported by the tool.
This does not depend on any kernel changes as support for both masked and
unmasked matches were added to the kernel at the same time.
Sample usage:
tc qdisc add dev eth0 ingress
tc filter add dev eth0 protocol ipv6 parent ffff: flower \
indev eth0 ip_proto icmpv6 type 128/240 code 0 action drop
Reposting after breaking out of a larger patchset.

tc: flower: provide generic masked u8 print helper
tc: flower: support masked ICMP code and type match
