net: macsec: remove the prepare phase when offloading

The hardware offloading in MACsec was initially supported using 2 phases.
This was proposed in the RFC as this could have allowed easier fallback
to the software implementation if the hardware did not support a feature
or had enough entries already. But this fallback wasn't implemented and
might not be a good idea after all. In addition it turned out this logic
didn't mapped well the hardware logic and device drivers were mostly
ignoring the preparation phase.

Let's remove this as it does not offer any advantage and is ignored by
drivers.

net: phy: Add support for rate matching

This adds support for rate matching (also known as rate adaptation) to
the phy subsystem. The general idea is that the phy interface runs at
one speed, and the MAC throttles the rate at which it sends packets to
the link speed. There's a good overview of several techniques for
achieving this at [1]. This patch adds support for three: pause-frame
based (such as in Aquantia phys), CRS-based (such as in 10PASS-TS and
2BASE-TL), and open-loop-based (such as in 10GBASE-W).

This patch makes a few assumptions and a few non assumptions about the
types of rate matching available. First, it assumes that different phys
may use different forms of rate matching. Second, it assumes that phys
can use rate matching for any of their supported link speeds (e.g. if a
phy supports 10BASE-T and XGMII, then it can adapt XGMII to 10BASE-T).
Third, it does not assume that all interface modes will use the same
form of rate matching. Fourth, it does not assume that all phy devices
will support rate matching (even if some do). Relaxing or strengthening
these (non-)assumptions could result in a different API. For example, if
all interface modes were assumed to use the same form of rate matching,
then a bitmask of interface modes supportting rate matching would
suffice.

For some better visibility into the process, the current rate matching
mode is exposed as part of the ethtool ksettings. For the moment, only
read access is supported. I'm not sure what userspace might want to
configure yet (disable it altogether, disable just one mode, specify the
mode to use, etc.). For the moment, since only pause-based rate
adaptation support is added in the next few commits, rate matching can
be disabled altogether by adjusting the advertisement.

802.3 calls this feature "rate adaptation" in clause 49 (10GBASE-R) and
"rate matching" in clause 61 (10PASS-TL and 2BASE-TS). Aquantia also calls
this feature "rate adaptation". I chose "rate matching" because it is
shorter, and because Russell doesn't think "adaptation" is correct in this
context.

Daniel Machon says:

====================
net: Add QoS offload support for sparx5

This patch series adds support for offloading QoS features with the tc
command suite, to the sparx5 switch. The new offloadable QoS features
introduced in this patch series are:

  - tc-mqprio for mapping traffic class to hardware queue. Queues are by
    default mapped 1:1  in hardware, as such the mqprio qdisc is used as
    an attachment point for qdiscs tbf and ets.

    $ tc qdisc add dev eth0 root handle 1:0 mqprio

  - tc-tbf for setting up shaping on scheduler elements of the HSCH
    (Hierarchical Scheduler) block. Shaping on either port output or
    queue output is supported.

    Port shaper: $ tc qdisc add dev eth0 root handle 1:0 tbf rate \
    10000000 burst 8192 limit 1m

    Queue shaper: $ tc qdisc replace dev eth0 parent 1:5 handle 2:0 tbf \
    rate 10000000 burst 8192 limit 1m

  - tc-ets for setting up strict and or bandwidth-sharing bands on one
    through eight priority queues.

    Configure a mix of strict and bw-sharing bands:
    $ tc qdisc add dev eth0 handle 1: root ets bands 8 strict 5 \
    quanta 1000 1000 1000 priomap 7 6 5 4 3 2 1 0

Patch #1 Sets up the tc hook.
Patch #2 Adds support for offloading the tc-mqprio qdisc.
Patch #3 Adds support for offloading the tc-tbf qdisc.
Patch #4 Adds support for offloading the tc-ets qdisc.
Patch #5 Updates the maintainers of the sparx5 driver.

Saeed Mahameed says:

====================
mlx5 MACSec Extended packet number and replay window offload

This is a follow up series to the previously submitted mlx5 MACsec offload [1]
earlier this release cycle.

In this series we add the support for MACsec Extended packet number and
replay window offloads.

First patch is a simple modification (code movements) to the core macsec code
to allow exposing the EPN related user properties to the offloading
device driver.

The rest of the patches are mlx5 specific, we start off with fixing some
trivial issues with mlx5 MACsec code, and a simple refactoring to allow
additional functionality in mlx5 macsec to support EPN and window replay
offloads.
 A) Expose mkey creation functionality to MACsec
 B) Expose ASO object to MACsec, to allow advanced steering operations,
    ASO objects are used to modify MACsec steering objects in fastpath.

1) Support MACsec offload extended packet number (EPN)

    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.

2) Support MACsec offload replay window

    Support setting replay window size for MACsec offload.
    Currently supported window size of 32, 64, 128 and 256
    bit. Other values will be returned as invalid parameter.

refactor duplicate codes in the qdisc class walk function

The walk implementation of most qdisc class modules is basically the
same. That is, the values of count and skip are checked first. If count
is greater than or equal to skip, the registered fn function is
executed. Otherwise, increase the value of count. So the code can be
refactored.

The walk function is invoked during dump. Therefore, test cases related
 to the tdc filter need to be added.
