The 128 bits ct_label field is matched using a 32 bit hardware register.
As such, only the lower 32 bits of ct_label field are offloaded. Change
this logic to support setting and matching higher bits too.
Map the 128 bits data to a unique 32 bits ID. Matching is done as exact
match of the mapping ID of key & mask.

On receive flow inspect received packets for IPsec offload indication
using the cqe, for IPsec offloaded packets propagate offload status
and stack handle to stack for further processing.
Supported statuses:
- Offload ok.
- Authentication failure.
- Bad trailer indication.
Connect-X IPsec does not use mlx5e_ipsec_handle_rx_cqe.
For RX only offload, we see the BW gain. Below is the iperf3

Introduce decrypt FT, the RX error FT and the default rules.
The IPsec RX decrypt flow table is pointed by the TTC
(Traffic Type Classifier) ESP steering rules.
The decrypt flow table has two flow groups. The first flow group
keeps the decrypt steering rule programmed via the "ip xfrm s" interface.
The second flow group has a default rule to forward all non-offloaded
ESP packet to the TTC ESP default RSS TIR.
The RX error flow table is the destination of the decrypt steering rules
in the IPsec RX decrypt flow table. It has a fixed rule with single
copy action that copies ipsec_syndrome to metadata_regB[0:6]. The IPsec
syndrome is used to filter out non-ipsec packet and to return the IPsec
crypto offload status in Rx flow. The destination of RX error flow table
is the TTC ESP default RSS TIR.
All the FTs (decrypt FT and error FT) are created only when IPsec SAs
are added. If there is no IPsec SAs, the FTs are removed.

This patch adds support for Connect-X IPsec crypto offload
by implementing the IPsec acceleration layer needed routines,
which delegates IPsec offloads to Connect-X routines.
In Connect-X IPsec, a Security Association (SA) is added or deleted
via allocating a HW context of an encryption/decryption key and
a HW context of a matching SA (IPsec object).
The Security Policy (SP) is added or deleted by creating matching Tx/Rx
steering rules whith an action of encryption/decryption respectively,
executed using the previously allocated SA HW context.
When new xfrm state (SA) is added:
- Use a separate crypto key HW context.
- Create a separate IPsec context in HW to inlcude the SA properties:
- aes-gcm salt.
- ICV properties (ICV length, implicit IV).
- on supported devices also update ESN.
- associate the allocated crypto key with this IPsec context.
Introduce a new compilation flag MLX5_IPSEC for it.
Downstream patches will implement the Rx,Tx steering
and will add the update esn.

Having the users of MSCC_OCELOT_SWITCH_LIB depend on REGMAP_MMIO was a
bad idea, since that symbol is not user-selectable. So we should have
kept a 'select REGMAP_MMIO'.
When we do that, we run into 2 more problems:
- By depending on GENERIC_PHY, we are causing a recursive dependency.
But it looks like GENERIC_PHY has no other dependencies, and other
drivers select it, so we can select it too:

- By depending on PHYLIB, we are causing a recursive dependency. PHYLIB
only has a single dependency, "depends on NETDEVICES", which we are
already depending on, so we can again hack our way into conformance by
turning the PHYLIB dependency into a select.

A busy-wait loop is used to implement waiting for bits to be copied
from the skb to the kernel buffer before retiring a block. This is
a problem on PREEMPT_RT because the copying task could be preempted
by the busy-waiting task and thus live lock in the busy-wait loop.
Replace the busy-wait logic with an rwlock_t. This provides lockdep
coverage and makes the code RT ready.

Initializing with 0 makes it much easier to identify time stamps from
otherwise uninitialized clock.
Initialization of PTP clock with current kernel time makes little sense as
PTP time scale differs from UTC time scale that kernel time represents.
It only leads to confusion when no actual PTP initialization happens, as
these time scales differ in a small integer number of seconds (37 at the
time of writing.)

mlxsw: Offload tc police action
This patch set adds support for tc police action in mlxsw.
Patches #1-#2 add defines for policer bandwidth limits and resource
identifiers (e.g., maximum number of policers).
Patch #3 adds a common policer core in mlxsw. Currently it is only used
by the policy engine, but future patch sets will use it for trap
policers and storm control policers. The common core allows us to share
common logic between all policer types and abstract certain details from
the various users in mlxsw.
Patch #4 exposes the maximum number of supported policers and their
current usage to user space via devlink-resource. This provides better
visibility and also used for selftests purposes.
Patches #5-#7 gradually add support for tc police action in the policy
engine by calling into previously mentioned policer core.
Patch #8 adds a generic selftest for tc-police that can be used with
veth pairs or physical loopbacks.
Patches #9-#11 add mlxsw-specific selftests.

In the policy engine, each ACL rule points to an action block where the
ACL actions are stored. Each action block consists of one or more action
sets. Each action set holds one or more individual actions, up to a
maximum queried from the device. For example:
Action set #1 Action set #2
+----------+ +--------------+ +--------------+
| ACL rule +----------> Action #1 | +-----> Action #4 |
+----------+ +--------------+ | +--------------+
| Action #2 | | | Action #5 |
+--------------+ | +--------------+
| Action #3 +------+ | |
+--------------+ +--------------+
<---------+ Action block +----------------->
The hardware has a limitation that prevents a policing action
(MLXSW_AFA_POLCNT_CODE when used with a policer, not a counter) from
being configured in the same action set with a trap action (i.e.,
MLXSW_AFA_TRAP_CODE or MLXSW_AFA_TRAPWU_CODE). Note that the latter used
to implement multiple actions: 'trap', 'mirred', 'drop'.
Work around this limitation by teaching mlxsw_afa_block_append_action()
to create a new action set not only when there is no more room left in
the current set, but also when there is a conflict between previously
mentioned actions.
