Add tc action flags when adding police action to offload meter table.
There is a restriction that the flag of skip_sw/skip_hw should be same for
filter rule and the independent created tc actions the rule uses. In this
case, if we configure the tc-policy as skip_hw, filter rule will be created
with skip_hw flag and the police action according to meter table will have
no action flag, then flower rule will fail to add to tc kernel system.
To fix this issue, we will add tc action flag when adding police action to
offload a meter table, so it will allow meter table to work in tc software
datapath.
Fixes: 5c039ddc64ff ("netdev-linux: Add functions to manipulate tc police action")

OVS has support for using policing to enforce a rate limit in
kilobits per second. This is configured using OVSDB. f.e.
$ ovs-vsctl set interface tap0 ingress_policing_rate=1000
$ ovs-vsctl set interface tap0 ingress_policing_burst=100
This patch adds a related feature, allowing policing to enforce a rate
limit in kilo-packets per second. This is also configured using OVSDB.
$ ovs-vsctl set interface tap0 ingress_policing_kpkts_rate=1000
$ ovs-vsctl set interface tap0 ingress_policing_kpkts_burst=100
The kilo-bit and kilo-packet rate limits may be used separately or in
combination.
Add separate action for BPS and PPS in netlink message.
Revise code and change action result to pipe to allow
traffic pipe into second action.
This patch implements the feature for:
* OVSDB (northbound API)
* TC policer when used both with and without TC offload (kernel API)

Recent changes in Linux kernel TC action subsystem introduced new
TCA_ACT_FLAGS_NO_PERCPU_STATS flag. The purpose of the flag is to request
action implementation to skip allocating action stats with expensive percpu
allocator and use regular built-in action stats instead. Such approach
significantly improves rule insertion rate and reduce memory usage for
hardware-offloaded rules that don't need benefits provided by percpu
allocated stats (improved software TC fast-path performance). Set the flag
for all compatible actions.
Modify acinclude.m4 to use OVS-internal pkt_cls.h implementation when
TCA_ACT_FLAGS is not defined by kernel headers and to manually define
struct nla_bitfield32 in netlink.h (new file) when it is not defined by
kernel headers.

In kernels older than 4.8, struct tcf_t didn't have the firstuse.
If openvswitch is compiled with the compat pkt_cls.h then there is
a struct size mismatch between openvswitch and the kernel which cause
parsing netlink actions to fail.
After this commit parsing the netlink actions pass even if compiled with
the compat pkt_cls.h.

Firstly this patch introduces the notion of reserved priority, as the
filter implementing ingress policing would require the highest priority.
Secondly it allows setting rate limiters while tc-offloads has been
enabled. Lastly it installs a matchall filter that matches all traffic
and then applies a police action, when configuring an ingress rate
limiter.
An example of what to expect:
OvS CLI:
ovs-vsctl set interface <netdev_name> ingress_policing_rate=5000
ovs-vsctl set interface <netdev_name> ingress_policing_burst=100
Resulting TC filter:
filter protocol ip pref 1 matchall chain 0
filter protocol ip pref 1 matchall chain 0 handle 0x1
not_in_hw
action order 1: police 0x1 rate 5Mbit burst 125Kb mtu 64Kb
action drop/continue overhead 0b
ref 1 bind 1 installed 3 sec used 3 sec
Action statistics:
Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0

Currently the inner VLAN header is ignored when using the TC data-path.
As TC flower supports QinQ, now we can offload the rules to match on both
outer and inner VLAN headers.

Added compatibility headers for actions vlan and tunnel key.
Do not use compat code when compiling kernel datapath
there is no need for it as TC compatibility is not provided there.
In other words, the compat code is only used when compiling user-space
code against old kernel headers.
