introduced in this patch series are:

    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

    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.

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.

bnxt_en: replace reset with config timestamps

Any change to the hardware timestamps configuration triggers nic restart,
which breaks transmition and reception of network packets for a while.
But there is no need to fully restart the device because while configuring
hardware timestamps. The code for changing configuration runs after all
of the initialisation, when the NIC is actually up and running. This patch
changes the code that ioctl will only update configuration registers and
will not trigger carrier status change, but in case of timestamps for
all rx packetes it fallbacks to close()/open() sequnce because of
synchronization issues in the hardware. Tested on BCM57504.

net: sunhme: Fix packet reception for len < RX_COPY_THRESHOLD

There is a separate receive path for small packets (under 256 bytes).
Instead of allocating a new dma-capable skb to be used for the next packet,
this path allocates a skb and copies the data into it (reusing the existing
sbk for the next packet). There are two bytes of junk data at the beginning
of every packet. I believe these are inserted in order to allow aligned DMA
and IP headers. We skip over them using skb_reserve. Before copying over
the data, we must use a barrier to ensure we see the whole packet. The
current code only synchronizes len bytes, starting from the beginning of
the packet, including the junk bytes. However, this leaves off the final
two bytes in the packet. Synchronize the whole packet.

To reproduce this problem, ping a HME with a payload size between 17 and
214

$ ping -s 17 <hme_address>

which will complain rather loudly about the data mismatch. Small packets
(below 60 bytes on the wire) do not have this issue. I suspect this is
related to the padding added to increase the minimum packet size.
