Offload action skbedit priority when keyed to a flower classifier. The
skb->priority field in Linux is very generic, so only allow setting the
bottom 8 priorities and bounce anything else.

The ACL flex action will have to know if it is in ingress or egress,
so it can use correct trap ID. Pass the ingress indication down to it.

In Spectrum-2, activity cannot be find out by TCAM rule (PTCEv2 register),
but rather by associated action set. For that purpose, extend action ops
to allow query activity from PEFA register. Block activity is decided
according to activity of the first set.

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e61 (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

Currently the only mirror action supported by mlxsw is mirror to another
mlxsw physical port. Correspondingly, span_entry, which tracks each
mlxsw mirror in the system, currently holds a u8 number of the
destination port.
To extend this system to mirror to gretap and ip6gretap netdevices, have
struct mlxsw_sp_span_entry actually hold the destination netdevice
itself.
This change then trickles down in obvious manner to SPAN module API and
mirror-related interfaces in struct mlxsw_afa_ops.
To prevent use of invalid pointer, NETDEV_UNREGISTER needs to be hooked
and the corresponding SPAN entry invalidated.

Instead of removing span_entry by the port number, allow removing by
SPAN id. That simplifies some code right here, and for mirroring to soft
netdevices, avoids problems with netdevice pointer invalidation and
reuse.
Rename mlxsw_sp_span_entry_find() to mlxsw_sp_span_entry_find_by_port()
and keep it--follow-up patches will make use of it.

So far, the caller of mlxsw_afa_block_append_counter needed to allocate
counter index by hand. Benefit from the previously introduced resource
infra and counter_index_get/put callbacks, and allocate the counter
index in place where it is needed, inside the action append function.

Use trap/discard flex action to implement trap and forward. The action will
later be used for multicast routing, as the multicast routing mechanism is
done using ACL flexible actions in Spectrum hardware. Using that action, it
will be possible to implement a trap-and-forward route.

Allow the trap ACL action to be configured with different traps. This
allows the multicast router offloading code to use that same ACL action
with the multicast router traps. By using different traps, the multicast
router can have different trap policies and can handle the packet
differently.

Each entry which is matched during ACL lookup points to an action set.
This action set contains up to three separate actions. If more actions
are needed to be chained, the extended set is created to hold them
in KVD linear area.
This patch implements handling of sets and encoding of actions.
Currectly, only two actions are supported. Drop and forward. Forward
action uses PBS pointer to KVD linear area, so the action code needs to
take care of this as well.
