668fd9b25d tc: m_tunnel_key: add options support for erpsan
This patch is to add TCA_TUNNEL_KEY_ENC_OPTS_ERSPAN's parse and
print to implement erspan options support in m_tunnel_key, like
Commit 6217917a38 ("tc: m_tunnel_key: Add tunnel option support
to act_tunnel_key") for geneve options support.

Option is expressed as version:index:dir:hwid, dir and hwid will
be parsed when version is 2, while index will be parsed when
version is 1. erspan doesn't support multiple options.

With this patch, users can add and dump erspan options like:

  # ip link add name erspan1 type erspan external
  # tc qdisc add dev eth0 ingress
  # tc filter add dev eth0 protocol ip parent ffff: \
      flower indev eth0 \
        ip_proto udp \
        action tunnel_key \
          set src_ip 10.0.99.192 \
          dst_ip 10.0.99.193 \
          dst_port 6081 \
          id 11 \
          erspan_opts 1:2:0:0 \
      action mirred egress redirect dev erspan1
  # tc -s filter show dev eth0 parent ffff:

     filter protocol ip pref 49151 flower chain 0 handle 0x1
       indev eth0
       eth_type ipv4
       ip_proto udp

         action order 1: tunnel_key  set
         src_ip 10.0.99.192
         dst_ip 10.0.99.193
         key_id 11
         dst_port 6081
         erspan_opts 1:2:0:0
         csum pipe
           index 2 ref 1 bind 1
         ...
v1->v2:
  - no change.
v2->v3:
  - no change.
v3->v4:
  - keep the same format between input and output, json and non json.
  - print version, index, dir and hwid as uint.

f72c3ad00f tc: m_tunnel_key: add options support for vxlan
This patch is to add TCA_TUNNEL_KEY_ENC_OPTS_VXLAN's parse and
print to implement vxlan options support in m_tunnel_key, like
Commit 6217917a38 ("tc: m_tunnel_key: Add tunnel option support
to act_tunnel_key") for geneve options support.

Option is expressed a 32bit number for gbp only, and vxlan
doesn't support multiple options.

With this patch, users can add and dump vxlan options like:

  # ip link add name vxlan1 type vxlan dstport 0 external
  # tc qdisc add dev eth0 ingress
  # tc filter add dev eth0 protocol ip parent ffff: \
      flower indev eth0 \
        ip_proto udp \
        action tunnel_key \
          set src_ip 10.0.99.192 \
          dst_ip 10.0.99.193 \
          dst_port 6081 \
          id 11 \
          vxlan_opts 65793 \
      action mirred egress redirect dev vxlan1
  # tc -s filter show dev eth0 parent ffff:

     filter protocol ip pref 49152 flower chain 0 handle 0x1
       indev eth0
       eth_type ipv4
       ip_proto udp
       not_in_hw
         action order 1: tunnel_key  set
         src_ip 10.0.99.192
         dst_ip 10.0.99.193
         key_id 11
         dst_port 6081
         vxlan_opts 65793
         ...

v1->v2:
  - get_u32 with base = 0 for gbp.
  - use to print_unint("0x%x") to print gbp.
v2->v3:
  - implement proper JSON array for opts.
v3->v4:
  - keep the same format between input and output, json and non json.
  - print gbp as uint.

dc0332b1e8 tc: m_tunnel_key: Allow key-less tunnels
Change the id parameter of the tunnel_key set action from mandatory to
optional.

Some tunneling protocols (e.g. GRE) specify the id as an optional field.

Allow to set tos and ttl for the tunnel.

For example, here's encap rule that sets tos to the tunnel:

   action tunnel_key set src_ip 192.168.10.1 dst_ip 192.168.10.2 id 100 dst_port 4789 tos 0x30 \
   action mirred egress redirect dev vxlan_sys_4789

d57639a475 tc/act_tunnel: Introduce ip tunnel action
This action could be used before redirecting packets to a shared tunnel
device, or when redirecting packets arriving from a such a device.

The 'unset' action is optional. It is used to explicitly unset the
metadata created by the tunnel device during decap. If not used, the
metadata will be released automatically by the kernel.
The 'set' operation, will set the metadata with the specified values for
the encap.

For example, the following flower filter will forward all ICMP packets
destined to 11.11.11.2 through the shared vxlan device 'vxlan0'. Before
redirecting, a metadata for the vxlan tunnel is created using the
tunnel_key action and it's arguments:

$ 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
