UMR MTTs used in striding RQ have certain alignment requirements. While
it's guaranteed to work when UMR pages are aligned to the UMR page size,
in practice it works then UMR pages are aligned to 8 bytes. However,
it's still not enough flexibility for the unaligned mode of XSK. This
patch leverages KSM to map UMR pages without alignment requirements,
when unaligned XSK is active. The downside is that KSM entries are twice
as big as MTTs, which limits the maximum WQE size, so regular RQs and
aligned XSK continue using MTTs.

This commit allows striding RQ to determine MTT page size at runtime,
instead of sticking to the compile-time PAGE_SIZE. This functionality
will be used by a following commit that adjusts the MTT page size to the
XSK frame size.
Stick with PAGE_SIZE for XSK on legacy RQ, as frag_stride is not used in
data path, it only helps calculate how pages are partitioned into
fragments, and PAGE_SIZE will ensure each fragment starts at the
beginning of a new allocation unit (XSK frame).

In hash mode, without setting tx affinity explicitly, the port select
flow table decides which port is used for the traffic.
If port_select_flow_table_bypass capability is supported and tx affinity
is set explicitly for QP/TIS, they will be added into the explicit affinity
table in FW to check which port is used for the traffic.
1. The overloaded explicit affinity table may affect performance.
To avoid this, do not set tx affinity explicitly by default.
2. The packets of the same flow need to be transmitted on the same port.
Because the packets of the same flow use different QPs in slow & fast
path, it shouldn't set tx affinity explicitly for these QPs.

MACsec EPN splits the packet number (PN) into two 32-bits fields,
epn_lsb (32 least significant bits (LSBs) of PN) and epn_msb (32
most significant bits (MSBs) of PN).
Epn_msb bits are managed by SW and for that HW is required to send
an object change event of type EPN event notifying the SW to update
the epn_msb in addition, once epn_msb is updated SW update HW with
the new epn_msb value for HW to perform replay protection.
To prevent HW from stopping while handling the event, SW manages
another bit for HW called epn_overlap, HW uses the latter to get
an indication regarding how to read the epn_msb value correctly
while still receiving packets.
Add epn event handling that updates the epn_overlap and epn_msb for
every 2^31 packets according to the following logic:
if epn_lsb crosses 2^31 (half sequence number wraparound) upon HW
relevant event, SW updates the esn_overlap value to OLD (value = 1).
When the epn_lsb crosses 2^32 (full sequence number wraparound)
upon HW relevant event, SW updates the esn_overlap to NEW
(value = 0) and increment the esn_msb.
When using MACsec EPN a salt and short secure channel id (ssci)
needs to be provided by the user, when offloading EPN need to pass
this salt and ssci to the HW to be used in the initial vector (IV)
calculations.

Tx flow steering consists of two flow tables (FTs).
The first FT (crypto table) has two fixed rules:
One default miss rule so non MACsec offloaded packets bypass the MACSec
tables, another rule to make sure that MACsec key exchange (MKE) traffic
passes unencrypted as expected (matched of ethertype).
On each new MACsec offload flow, a new MACsec rule is added.
This rule is matched on metadata_reg_a (which contains the id of the
flow) and invokes the MACsec offload action on match.
The second FT (check table) has two fixed rules:
One rule for verifying that the previous offload actions were
finished successfully and packet need to be transmitted.
Another default rule for dropping packets that were failed in the
offload actions.
The MACsec FTs should be created on demand when the first MACsec rule is
added and destroyed when the last MACsec rule is deleted.

When the RDMA auxiliary driver probes, it sets its profile based on
devlink driverinit value. The latter might not be in sync with FW yet
(In case devlink reload is not performed), thus causing a mismatch
between RDMA driver and FW. This results in the following FW syndrome
when the RDMA driver tries to adjust RoCE state, which fails the probe:
"0xC1F678 | modify_nic_vport_context: roce_en set on a vport that
doesn't support roce"
To prevent this, select the PF profile based on FW RoCE capability
instead of relying on devlink driverinit value.
To provide backward compatibility of the RoCE disable feature, on older
FW's where roce_rw is not set (FW RoCE capability is read-only), keep
the current behavior e.g., rely on devlink driverinit value.

Add capability field which indicates the mask for wqe_counter which
connects between loopback CQE and the original WQE. With this connection
the driver can identify lost of the loopback CQE and reply PTP
synchronization with timestamp given in the original CQE.

Use software VHCA id when it's supported by the firmware.
A unique id is allocated upon mlx5_mdev_init() and freed upon
mlx5_mdev_uninit(), as such it stays the same during the full life cycle
of the device including upon health recovery if occurred.
The conjunction of sw_vhca_id with sw_owner_id will be a global unique
id per function which uses mlx5_core.
The sw_vhca_id is set upon init_hca command and is used to specify the
VHCA that the NIC vport is affiliated with.
This functionality is needed upon migration of VM which is MPV based.
(i.e. multi port device).

As part of the flows invoked by mlx5_devlink_eswitch_mode_set() get to
mlx5_rescan_drivers_locked() which can call mlx5e_probe()/mlx5e_remove
and register/unregister mlx5e driver ports accordingly. This can lead to
deadlock once mlx5_devlink_eswitch_mode_set() will use devlink lock.
Use devl_port_register/unregister() instead of
devlink_port_register/unregister() and add devlink instance locks in the
driver paths to this function to have it locked while calling devl_ API
function.
If remove or probe were called by module init or module cleanup flows,
need to lock devlink just before calling devl_port_register(), otherwise
it is called by attach/detach or register/unregister flow and we can
have the flow locked. Added flag to distinguish between these cases.
This will be used by the downstream patch to invoke
mlx5_devlink_eswitch_mode_set() with devlink locked.

Currently, there are three eswitch modes, none, legacy and switchdev.
None is the default mode. Remove redundant none mode as eswitch mode
should always be either legacy mode or switchdev mode.
With this patch, there are two behavior changes:
1. Legacy becomes the default mode. When querying eswitch mode using
devlink, a valid mode is always returned.
2. When disabling sriov, the eswitch mode will not change, only vfs
are unloaded.
