[PATCH/RFC net-next 0/2] net/sched: cls_flower: Support matching on ND

[Simon Horman <simon.horman@netronome.com>]

Allow matching on Neighbour Discovery target IP, and source and
destination link-layer addresses for neighbour solicitation and
advertisement messages.

This is achieved by enhancing the flow dissector.

Sample usage:

tc qdisc add dev eth0 ingress

tc filter add dev eth0 protocol ipv6 parent ffff: flower \
	indev eth0 ip_proto icmpv6 type 136 code 0 \
	nd_target 2001:470:7eb3:403:201:8eff:fe22:8fea \
	nd_tll 00:01:8e:22:8f:ea action drop


Dependency:

This series depends on the following patch which is present in net
040587af3122 ("net/sched: cls_flower: Correct matching on ICMPv6 code")
