mlxsw: Add tunnel devlink-trap support

This patch set from Amit adds support in mlxsw for tunnel traps and a
few additional layer 3 traps that can report drops and exceptions via
devlink-trap.

These traps allow the user to more quickly diagnose problems relating to
tunnel decapsulation errors, such as packet being too short to
decapsulate or a packet containing wrong GRE key in its GRE header.

Patch set overview:

Patches #1-#4 add three additional layer 3 traps. Two of which are
mlxsw-specific as they relate to hardware-specific errors. The patches
include documentation of each trap and selftests.

Patches #5-#8 are preparations. They ensure that the correct ECN bits
are set in the outer header during IPinIP encapsulation and that packets
with an invalid ECN combination in underlay and overlay are trapped to
the kernel and not decapsulated in hardware.

Patches #9-#15 add support for two tunnel related traps. Each trap is
documented and selftested using both VXLAN and IPinIP tunnels, if
applicable.

====================
Mellanox, mlx5 E-Switch chains and prios

This series has two parts,

1) A merge commit with mlx5-next branch that include updates for mlx5
HW layouts needed for this and upcoming submissions.

2) From Paul, Increase the number of chains and prios

Currently the Mellanox driver supports offloading tc rules that
are defined on the first 4 chains and the first 16 priorities.
The restriction stems from the firmware flow level enforcement
requiring a flow table of a certain level to point to a flow
table of a higher level. This limitation may be ignored by setting
the ignore_flow_level bit when creating flow table entries.
Use unmanaged tables and ignore flow level to create more tables than
declared by fs_core steering. Manually manage the connections between the
tables themselves.

HW table is instantiated for every tc <chain,prio> tuple. The miss rule
of every table either jumps to the next <chain,prio> table, or continues
to slow_fdb. This logic is realized by following this sequence:

1. Create an auto-grouped flow table for the specified priority with
    reserved entries

Reserved entries are allocated at the end of the flow table.
Flow groups are evaluated in sequence and therefore it is guaranteed
that the flow group defined on the last FTEs will be the last to evaluate.

Define a "match all" flow group on the reserved entries, providing
the platform to add table miss actions.

2. Set the miss rule action to jump to the next <chain,prio> table
    or the slow_fdb.

3. Link the previous priority table to point to the new table by
    updating its miss rule.

Please pull and let me know if there's any problem.

T6 can support 2 egress traffic management channels per port to
double the total number of traffic classes that can be configured.
In this configuration, if the class belongs to the other channel,
then all the queues must be bound again explicitly to the new class,
for the rate limit parameters on the other channel to take effect.

So, always explicitly bind all queues to the port rate limit traffic
class, regardless of the traffic management channel that it belongs
to. Also, only bind queues to port rate limit traffic class, if all
the queues don't already belong to an existing different traffic
class.

Rate adaptation for Felix DSA switch

When operating the MAC at 2.5Gbps (2500Base-X and USXGMII/QSXGMII) and
in combination with certain PHYs, it is possible that the copper side
may operate at lower link speeds. In this case, it is the PHY who has a
MAC inside of it that emits pause frames towards the switch's MAC,
telling it to slow down so that the transmission is lossless.

These patches are the support needed for the switch side of things to
work.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

If the serdes link is set to 2500 using interfce type 2500base-X, lower
link speeds over on the line side should still be supported.
Rate adaptation is done out of band, in our case using AQR PHYs this is
done using flow control.

Flow control is used with 2500Base-X and AQR PHYs to do rate adaptation
between line side 100/1000 links and MAC running at 2.5G.

This is independent of the flow control configuration settled on line
side though AN.

In general, allowing the MAC to handle flow control even if not
negotiated with the link partner should not be a problem, so the patch
just enables it in all cases.
