mlxsw used to hold an array of qdiscs indexed by the TC number. In the
previous patch, it was changed to allocate child qdiscs dynamically, and
they are now indexed by band number. Follow suit with the array of future
FIFOs.

Instead of keeping qdiscs in globally-preallocated arrays, introduce a
per-qdisc-kind value num_classes, and then allocate the necessary child
qdiscs (if any) based on that value. Since now dynamic allocation is
involved, mlxsw_sp_qdisc_replace() gets messy enough that it is worth it to
split it to two cases: a new qdisc allocation and a change of existing
qdisc. (Note that the change also includes what TC formally calls replace,
if the qdisc kind is the same.)

The FIFO handler currently guards accesses to the future FIFO tracking by
asserting RTNL. In the future, the changes to the qdisc state will be more
thorough, so other qdiscs will need this guarding is as well. In order
to not further the RTNL infestation, instead convert to a custom lock that
will guard accesses to the qdisc state.

mlxsw currently allows a two-level structure of qdiscs: the root and
possibly a number of children. In order to support offloading more general
qdisc trees, introduce to struct mlxsw_sp_qdisc a pointer to child qdiscs.
Refer to the child qdiscs through this pointer, instead of going through
the tclass_qdiscs in qdisc_state. Additionally introduce a field
num_classes, which holds number of given qdisc's children.
Also introduce a generic function for walking qdisc trees. Rewrite
mlxsw_sp_qdisc_find() and _find_by_handle() to use the generic walker.
For now, keep the qdisc_state.tclass_qdisc, and just point root_qdiscs's
children to this array. Following patches will make the allocation dynamic.

When a qdisc is removed, it is necessary to update the backlog value at its
parent--unless the qdisc is at root position. RED, TBF and FIFO all do
that, each separately. Since all of them need to do this, just promote the
operation directly to mlxsw_sp_qdisc_destroy(), instead of deferring it to
individual destructors. Since FIFO dtor thus becomes trivial, remove it.
Add struct mlxsw_sp_qdisc.parent to point at the parent qdisc. This will be
handy later as deeper structures are offloaded. Use the parent qdisc to
find the chain of parents whose backlog value needs to be updated.

The purpose of this function is to filter out events that are related to
qdiscs that are not offloaded, or are not offloaded anymore. But the
function is unnecessarily thorough:
- mlxsw_sp_qdisc pointer is never NULL in the context where it is called
- Two qdiscs with the same handle will never have different types. Even
when replacing one qdisc with another in the same class, Linux will not
permit handle reuse unless the qdisc type also matches.
Simplify the function by omitting these two unnecessary conditions.

Register 27_6.15:14 has the following description in 88E6393X
documentation:
Temperature Sensor Enable
0x0 - Sample every 1s
0x1 - Sense rate decided by bits 10:8 of this register
0x2 - Use 26_6.5 (One shot Temperature Sample) to enable
0x3 - Disable
This is compatible with how the 6390 code uses this register currently,
but the 6390 code handles it as two 1-bit registers (somewhat), instead
of one register with 4 possible values.
(A newer version of the 6390 documentation removed temperature sensor
section completely. In an older version, the above mentioned register
is reserved, although it is R/W. Since the code works, I think we can
assume that it is correct.)
Rename this register and define all 4 values according to 6393X
documentation.

mlx5-updates-2021-04-19
This patchset provides some updates to mlx5e and mlx5 SW steering drivers:
1) Tariq and Vladyslav they both provide some trivial update to mlx5e netdev.
The next 12 patches in the patchset are focused toward mlx5 SW steering:
2) 3 trivial cleanup patches
3) Dynamic Flex parser support:
Flex parser is a HW parser that can support protocols that are not
natively supported by the HCA, such as Geneve (TLV options) and GTP-U.
There are 8 such parsers, and each of them can be assigned to parse a
specific set of protocols.
4) Enable matching on Geneve TLV options
5) Use Flex parser for MPLS over UDP/GRE
6) Enable matching on tunnel GTP-U and GTP-U first extension
header using
7) Improved QoS for SW steering internal QPair for a better insertion rate

ALWAYS_GUARD_BAND_SCH_Q bit in TAS config register is descripted as
this:
0: Guard band is implemented for nonschedule queues to schedule
queues transition.
1: Guard band is implemented for any queue to schedule queue
transition.
The driver set guard band be implemented for any queue to schedule queue
transition before, which will make each GCL time slot reserve a guard
band time that can pass the max SDU frame. Because guard band time could
not be set in tc-taprio now, it will use about 12000ns to pass 1500B max
SDU. This limits each GCL time interval to be more than 12000ns.
This patch change the guard band to be only implemented for nonschedule
queues to schedule queues transition, so that there is no need to reserve
guard band on each GCL. Users can manually add guard band time for each
schedule queues in their configuration if they want.

When using SW steering, rule insertion rate depends on the RDMA RC QP
performance used for writing to the ICM. During stress this QP is competing
on the HW resources with all the other QPs that are used to send data.
To protect SW steering QP's performance in such cases, we set this QP to
use isolated VL. The VL number is reserved by FW and is not exposed to the
driver.
Support for this QP on isolated VL exists only when both force-loopback and
isolate_vl_tc capabilities are set.
