Lay the groundwork for Spectrum-2 support. On Spectrum-2, the packets get
the time stamps from the CQE, which means that the time stamp is attached
to its packet.
Configure MTPTPT to set which message types should arrive under which
PTP trap. PTP0 will be used for event message types, which means that
the packets require time stamp. PTP1 will be used for other packets.
Note that in Spectrum-2, all packets contain time stamp by default. The two
types of traps (PTP0, PTP1) will be used to separate between PTP_EVENT
traps and PTP_GENERAL traps, so then the driver will fill the time stamp as
part of the SKB only for event message types.
Later the driver will enable the traps using 'MTPCPC.ptp_trap_en' bit.
Then, PTP packets start arriving through the PTP traps.
Currently, the structure 'mlxsw_sp2_ptp_state' contains only the common
structure, the next patches will extend it.

Currently, Tx completions are reported using Completion Queue Element
version 1 (CQEv1). These elements do not contain the Tx time stamp,
which is fine as Spectrum-1 reads Tx time stamps via a dedicated FIFO
and Spectrum-2 does not currently support PTP.
In preparation for Spectrum-2 PTP support, use CQEv2 for Spectrum-2 and
newer ASICs, as this CQE format encodes the Tx time stamp.

MTPTPT register is used to set which message types should arrive under
which PTP trap. Currently, PTP0 is used for event message types, which
means that the packets require time stamp. PTP1 is used for other packets.
This configuration will be same for Spectrum-2 and newer ASICs. In
preparation for Spectrum-2 PTP support, add helper functions to
configure PTP traps and use them for Spectrum-1. These functions will be
used later also for Spectrum-2.

Aside of urb->transfer_buffer_length and urb->context which might
change in the TX path, all the other URB parameters remains constant
during runtime. So, there is no reasons to call usb_fill_bulk_urb()
each time before submitting an URB.
Make sure to initialize all the fields of the URB at allocation
time. For the TX branch, replace the call usb_fill_bulk_urb() by an
assignment of urb->context. urb->urb->transfer_buffer_length is
already set by the caller functions, no need to set it again. For the
RX branch, because all parameters are unchanged, simply remove the
call to usb_fill_bulk_urb().

Let the TLS TX recycle pool be more flexible in size, by continuously
and dynamically allocating and releasing HW resources in response to
changes in the connections rate and load.
Allocate and release pool entries in bulks (16). Use a workqueue to
release/allocate in the background. Allocate a new bulk when the pool
size goes lower than the low threshold (1K). Symmetric operation is done
when the pool size gets greater than the upper threshold (4K).
Every idle pool entry holds: 1 TIS, 1 DEK (HW resources), in addition to
~100 bytes in host memory.
Start with an empty pool to minimize memory and HW resources waste for
non-TLS users that have the device-offload TLS enabled.
Upon a new request, in case the pool is empty, do not wait for a whole bulk
allocation to complete. Instead, trigger an instant allocation of a single
resource to reduce latency.
Performance tests:
Before: 11,684 CPS
After: 16,556 CPS

The transport interface send (TIS) object is responsible for performing
all transport related operations of the transmit side. The ConnectX HW
uses a TIS object to save and access the TLS crypto information and state
of an offloaded TX kTLS connection.
Before this patch, we used to create a new TIS per connection and destroy
it once it’s closed. Every create and destroy of a TIS is a FW command.
Same applies for the private TLS context, where we used to dynamically
allocate and free it per connection.
Resources recycling reduce the impact of the allocation/free operations
and helps speeding up the connection rate.
In this feature we maintain a pool of TX objects and use it to recycle
the resources instead of re-creating them per connection.
A cached TIS popped from the pool is updated to serve the new connection
via the fast-path HW interface, updating the tls static and progress
params. This is a very fast operation, significantly faster than FW
commands.
On recycling, a WQE fence is required after the context params change.
This guarantees that the data is sent after the context has been
successfully updated in hardware, and that the context modification
doesn't interfere with existing traffic.
