61e8655cfc tc: Add VLAN tpid for push action
Currently we only support 802.1q, so we can offload push action without
specifying any vlan type. Kernel will push 802.1q ethertype by default.

But to support QinQ, we need to tell what ethertype is in push action as
it could be 802.1ad.

093c9458fb tc: allow offloading of block ids
Blocks, in tc classifiers, allow the grouping of multiple qdiscs with an
associated block id. Whenever a filter is added to/removed from this
block, the filter is added to/removed from all associated qdiscs.

Extend TC offload functions to take a block id as a parameter. If the id
is zero then the dqisc is not considered part of a block.

d63ca5329f dpctl: Properly reflect a rule's offloaded to HW state
Previously, any rule that is offloaded via a netdev, not necessarily
to the HW, would be reported as "offloaded". This patch fixes this
misalignment, and introduces the 'dp' state, as follows:

rule is in HW via TC offload  -> offloaded=yes dp:tc
rule is in not HW over TC DP  -> offloaded=no  dp:tc
rule is in not HW over OVS DP -> offloaded=no  dp:ovs

To achieve this, the flows's 'offloaded' flag was encapsulated in a new
attrs struct, which contains the offloaded state of the flow and the
DP layer the flow is handled in, and instead of setting the flow's
'offloaded' state based solely on the type of dump it was acquired
via, for netdev flows it now sends the new attrs struct to be
collected along with the rest of the flow via the netdev, allowing
it to be set per flow.

For TC offloads, the offloaded state is set based on the 'in_hw' and
'not_in_hw' flags received from the TC as part of the flower. If no
such flag was received, due to lack of kernel support, it defaults
to true.

0c70132cd2 tc: Make the actions order consistent
When OVS DP passes the actions to TC library, we save all the
actions in data structure tc_flower and each action type has its
own field in tc_flower. So when TC library passes the actions to
kernel, actually the actions order is lost.

We add an actions array in tc_flower to keep the actions order
in this patch.

b2befd5bb2 sparse: Add guards to prevent FreeBSD-incompatible #include order.
FreeBSD insists that <sys/types.h> be included before <netinet/in.h> and
that <netinet/in.h> be included before <arpa/inet.h>.  This adds guards to
the "sparse" headers to yield a warning if this order is violated.  This
commit also adjusts the order of many #includes to suit this requirement.

de4a611f9c tc: Fix compile with Glibc < 2.24 and Linux > 4.5.
linux/pkt_cls.h indirectly includes linux/stddef.h, which may define
__always_inline when using Linux kernel headers 4.6 or later.

netinet/in.h indirectly includes sys/cdefs.h, which before Glibc 2.24
would unconditionally define __always_inline.

This combination of headers causes compilation failure. Resolve the
issue by placing the netinet/in.h include above linux/pkt_cls.h.
