Subject: [PATCH iproute2 0/2] tc/cls_flower: Support for ip tunnel metadata set/release/classify

Hi,

This short series adds support for matching and setting metadata for ip tunnel
shared device using the TC system, introduced in kernel 4.9 [1].

Applied and tested on top of commit f3f339e9590a ("cleanup debris from revert")

Example usage:

$ tc filter add dev vxlan0 protocol ip parent ffff: \
    flower \
      enc_src_ip 11.11.0.2 \
      enc_dst_ip 11.11.0.1 \
      enc_key_id 11 \
      dst_ip 11.11.11.1 \
    action tunnel_key release \
    action mirred egress redirect dev vnet0

$ tc filter add dev net0 protocol ip parent ffff: \
    flower \
      ip_proto 1 \
      dst_ip 11.11.11.2 \
    action tunnel_key set \
      src_ip 11.11.0.1 \
      dst_ip 11.11.0.2 \
      id 11 \
    action mirred egress redirect dev vxlan0

Thanks,
Amir
