Fix max_rate option in TC, check for proper quanta boundaries.
Check for minimum value provided and if it fits expected 50Mbps
quanta.
Without this patch, iavf could send settings for max_rate limiting
that would be accepted from by PF even the max_rate option is less
than expected 50Mbps quanta. It results in no rate limiting
on traffic as rate limiting will be floored to 0.
Example:
tc qdisc add dev $vf root mqprio num_tc 3 map 0 2 1 queues \
2@0 2@2 2@4 hw 1 mode channel shaper bw_rlimit \
max_rate 50Mbps 500Mbps 500Mbps
Should limit TC0 to circa 50 Mbps
tc qdisc add dev $vf root mqprio num_tc 3 map 0 2 1 queues \
2@0 2@2 2@4 hw 1 mode channel shaper bw_rlimit \
max_rate 0Mbps 100Kbit 500Mbps
Should return error

The naming of the get/set/clear firmware feature capability bits doesn't
really follow the established namespace pattern of
wcn36xx_logicalblock_do_something();
The feature bits are accessed by smd.c and main.c. It would be nice to
display the found feature bits in debugfs. To do so though we should tidy
up the namespace a bit.
Move the firmware feature exchange API to its own file - firmware.c giving

The previous patch ("netdevsim: fib: Fix reference count leak on route

Such failures can only be simulated by injecting slab allocation
failures, which cannot be surgically injected.

As part of FIB offload simulation, netdevsim stores IPv4 and IPv6 routes
and holds a reference on FIB info structures that in turn hold a
reference on the associated nexthop device(s).
In the unlikely case where we are unable to allocate memory to process a
route deletion request, netdevsim will not release the reference from
the associated FIB info structure, thereby preventing the associated
nexthop device(s) from ever being removed [1].
Fix this by scheduling a work item that will flush netdevsim's FIB table
upon route deletion failure. This will cause netdevsim to release its
reference from all the FIB info structures in its table.

The 'get_ts_info' callback is used for obtaining information about
time stamping and PTP hardware clock capabilities of a network device.
The existing function of Spectrum-1 is used to advertise the PHC
capabilities and the supported RX and TX filters. Implement a similar
function for Spectrum-2, expose that the supported 'rx_filters' are all
PTP event packets, as for these packets the driver fills the time stamp
from the CQE in the SKB.
In the future, mlxsw driver will be extended to support one-step PTP in
Spectrum-2 and newer ASICs. Then additional 'tx_types' will be supported.

The SIOCSHWTSTAMP ioctl configures HW timestamping on a given port. In
Spectrum-2 and above, each packet gets time stamp by default, but in
order to provide an accurate time stamp, software should configure to
update the correction field. In addition, the PTP traps are not enabled
by default, software should enable it per port or for all ports.
The switch behaves like a transparent clock between CPU port and each
front panel port. If ingress correction is set on a port for a given packet
type, then when such a packet is received via the port, the current time
stamp is subtracted from the correction field. If egress correction is set
on a port for a given packet type, then when such a packet is transmitted
via the port, the current time stamp is added to the correction field.
The result is that as the packet ingresses through a port with ingress
correction enabled, and egresses through a port with egress correction
enabled, the PTP correction field is updated to reflect the time that the
packet spent in the ASIC.
This can be used to update the correction field of trapped packets by
enabling ingress correction on a port where time stamping was enabled,
and egress correction on the CPU port. Similarly, for packets transmitted
from the host, ingress correction should be enabled on the CPU port, and
egress correction on a front-panel port.
However, since the correction fields will be updated for all PTP packets
crossing the CPU port, in order not to mangle the correction field, the
front panel port involved in the packet transfer must have the
corresponding correction enabled as well.
Therefore, when HW timestamping is enabled on at least one port, we have
to configure hardware to update the correction field and trap PTP event
packets on all ports.
Add reference count as part of 'struct mlxsw_sp_ptp_state', to maintain
how many ports use HW timestamping. Handle the correction field
configuration only when the first port enables time stamping and when the
last port disables time stamping. Store the configuration as part of
'struct mlxsw_sp_ptp_state', as it is global for all ports.
The SIOCGHWTSTAMP ioctl is a getter for the current configuration,
implement it and use the global configuration.

As opposed to Spectrum-1, in which time stamps arrive through a pair of
dedicated events into a queue and later are being matched to the
corresponding packets, in Spectrum-2 we are reading the time stamps
directly from the CQE. Software can get the time stamp in UTC format
using CQEv2.
Add a time stamp field to 'struct mlxsw_skb_cb'. In
mlxsw_pci_cqe_{rdq,sdq}_handle() extract the time stamp from the CQE into
the new time stamp field. Note that the time stamp in the CQE is
represented by 38 bits, which is a short representation of UTC time.
Software should create the full time stamp using the global UTC clock.
Read UTC clock from hardware only for PTP packets which were trapped to CPU
with PTP0 trap ID (event packets).
Use the time stamp from the SKB when packet is received or transmitted.

In Spectrum-2 and Spectrum-3, the correction field of PTP packets which are
sent as control packets is not updated at egress port. To overcome this
limitation, PTP packets which require time stamp, should be sent as data
packets with the following details:
1. FID valid = 1
2. FID value above the maximum FID
3. rx_router_port = 1
>From Spectrum-4 and on, this limitation will be solved.
Extend the function which handles TX header, in case that the packet is
a PTP packet, add TX header with type=data and all the above mentioned
requirements. Add operation as part of 'struct mlxsw_sp_ptp_ops', to be
able to separate the handling of PTP packets between different ASICs. Use
the data packet solution only for Spectrum-2 and Spectrum-3. Therefore, add
a dedicated operation structure for Spectrum-4, as it will be same to
Spectrum-2 in PTP implementation, just will not have the limitation of
control packets.

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.

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.
