mlx5 TLS TX HW offload support
This series from Eran and me, adds TLS TX HW offload support to
the mlx5 driver.
This offloads the kTLS encryption process from kernel to the
Mellanox NIC, saving CPU cycles and improving utilization.
Upon a new TLS connection request, driver is responsible to create
a dedicated HW context and configure it according to the crypto info,
so HW can do the encryption itself.
When the HW context gets out-of-sync (i.e. due to packets retransmission),
driver is responsible for the re-sync process.
This is done by posting special resync descriptors to the HW.
Feature is supported on Mellanox Connect-X 6DX, and newer.
Series was tested on SimX simulator.

Add support for transmit side kernel-TLS acceleration.
Offload the crypto encryption to HW.
Per TLS connection:
- Use a separate TIS to maintain the HW context.
- Use a separate encryption key.
- Maintain static and progress HW contexts by posting the proper
WQEs at creation time, or upon resync.
- Use a special DUMP opcode to replay the previous frags and sync
the HW context.
To make sure the SQ is able to serve an xmit request, increase
SQ stop room to cover:
- static params WQE,
- progress params WQE, and
- resync DUMP per frag.
Currently supporting TLS 1.2, and key size 128bit.
Tested over SimX simulator.

Both ip_neigh_gw4() and ip_neigh_gw6() can return either a valid pointer
or an error pointer, but the code currently checks that the pointer is
not NULL.
Fix this by checking that the pointer is not an error pointer, as this
can result in a NULL pointer dereference [1]. Specifically, I believe
that what happened is that ip_neigh_gw4() returned '-EINVAL'
(0xffffffffffffffea) to which the offset of 'refcnt' (0x70) was added,
which resulted in the address 0x000000000000005a.

Quoting Arnd,
We have to do a sync_single_for_device /somewhere/ before the
buffer is given to the device. On a non-cache-coherent machine with
a write-back cache, there may be dirty cache lines that get written back
after the device DMA's data into it (e.g. from a previous memset
from before the buffer got freed), so you absolutely need to flush any
dirty cache lines on it first.
Since the coherency is configurable in this device make sure we cover
all configurations by explicitly syncing the allocated buffer for the
device before refilling it's descriptors

mlxsw: Enable/disable PTP shapers
Shalom says:
In order to get more accurate hardware time stamping in Spectrum-1, the
driver needs to apply a shaper on the port for speeds lower than 40Gbps.
This shaper is called a PTP shaper and it is applied on hierarchy 0,
which is the port hierarchy. This shaper may affect the shaper rates of
all hierarchies.
This patchset adds the ability to enable or disable the PTP shaper on
the port in two scenarios:
1. When the user wants to enable/disable the hardware time stamping
2. When the port is brought up or down (including port speed change)
Patch #1 adds the QEEC.ptps field that is used for enabling or disabling
the PTP shaper on a port.
Patch #2 adds a note about disabling the PTP shaper when calling to
mlxsw_sp_port_ets_maxrate_set().
Patch #3 adds the QPSC register that is responsible for configuring the
PTP shaper parameters per speed.
Patch #4 sets the PTP shaper parameters during the ptp_init().
Patch #5 adds new operation for getting the port's speed.
Patch #6 enables/disables the PTP shaper when turning on or off the
hardware time stamping.
Patch #7 enables/disables the PTP shaper when the port's status has
changed (including port speed change).
Patch #8 applies the PTP shaper enable/disable logic by filling the PTP
shaper parameters array.
