a2e02f38ef Bluetooth: hci_ll: set operational frequency earlier
Uploading the firmware needs quite a few seconds if done at 115200 kbps. So set
the operational frequency, usually 3 MHz, before uploading the firmware.

I have successfully tested this with a wl1837mod.

23f30c41c7 Merge branch 'mlx5-TLS-TX-HW-offload-support'
Tariq Toukan says:

====================
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.

Series generated against net-next commit [1], with Saeed's request pulled [2]:

d2ead1f360 net/mlx5e: Add kTLS TX HW offload support
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.

cd1973a921 net: netsec: Sync dma for device on buffer allocation
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.

8338d93788 net/mlx5: Added devlink info callback
The callback is invoked using 'devlink dev info <pci>' command and returns
the running and pending firmware version of the HCA and the name of the
kernel driver.

If there is a pending firmware version (a new version is burned but the
HCA still runs with the previous) it is returned as the stored
firmware version. Otherwise, the running version is returned for this
field.

Output example:
$ devlink dev info pci/0000:00:06.0
pci/0000:00:06.0:
  driver mlx5_core
  versions:
      fixed:

9c86b07e30 net/mlx5: Added fw version query command
Using the MCQI and MCQS registers, we query the running and pending
fw version of the HCA.
The MCQS is queried with sequentially increasing component index, until
a component of type BOOT_IMG is found. Querying this component's version
using the MCQI register yields the running and pending fw version of the
HCA.

Querying MCQI for the pending fw version should be done only after
validating that such fw version exists. This is done my checking
'component update state' field in MCQS output.

pull-request: bpf-next 2019-07-03

The following pull-request contains BPF updates for your *net-next* tree.

There is a minor merge conflict in mlx5 due to 8960b38932 ("linux/dim:
Rename externally used net_dim members") which has been pulled into your
tree in the meantime, but resolution seems not that bad ... getting current
bpf-next out now before there's coming more on mlx5. ;) I'm Cc'ing Saeed
just so he's aware of the resolution below:

** First conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c:

  <<<<<<< HEAD
  static int mlx5e_open_cq(struct mlx5e_channel *c,
                           struct dim_cq_moder moder,
                           struct mlx5e_cq_param *param,
                           struct mlx5e_cq *cq)
  =======
  int mlx5e_open_cq(struct mlx5e_channel *c, struct net_dim_cq_moder moder,
                    struct mlx5e_cq_param *param, struct mlx5e_cq *cq)
  >>>>>>> e5a3e259ef

Resolution is to take the second chunk and rename net_dim_cq_moder into
dim_cq_moder. Also the signature for mlx5e_open_cq() in ...

  drivers/net/ethernet/mellanox/mlx5/core/en.h +977

... and in mlx5e_open_xsk() ...

  drivers/net/ethernet/mellanox/mlx5/core/en/xsk/setup.c +64

... needs the same rename from net_dim_cq_moder into dim_cq_moder.

** Second conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c:

  <<<<<<< HEAD
          int cpu = cpumask_first(mlx5_comp_irq_get_affinity_mask(priv->mdev, ix));
          struct dim_cq_moder icocq_moder = {0, 0};
          struct net_device *netdev = priv->netdev;
          struct mlx5e_channel *c;
          unsigned int irq;
  =======
          struct net_dim_cq_moder icocq_moder = {0, 0};
  >>>>>>> e5a3e259ef

Take the second chunk and rename net_dim_cq_moder into dim_cq_moder
as well.

Let me know if you run into any issues. Anyway, the main changes are:

1) Long-awaited AF_XDP support for mlx5e driver, from Maxim.

2) Addition of two new per-cgroup BPF hooks for getsockopt and
   setsockopt along with a new sockopt program type which allows more
   fine-grained pass/reject settings for containers. Also add a sock_ops
   callback that can be selectively enabled on a per-socket basis and is
   executed for every RTT to help tracking TCP statistics, both features
   from Stanislav.

3) Follow-up fix from loops in precision tracking which was not propagating
   precision marks and as a result verifier assumed that some branches were
   not taken and therefore wrongly removed as dead code, from Alexei.

4) Fix BPF cgroup release synchronization race which could lead to a
   double-free if a leaf's cgroup_bpf object is released and a new BPF
   program is attached to the one of ancestor cgroups in parallel, from Roman.

5) Support for bulking XDP_TX on veth devices which improves performance
   in some cases by around 9%, from Toshiaki.

6) Allow for lookups into BPF devmap and improve feedback when calling into
   bpf_redirect_map() as lookup is now performed right away in the helper
   itself, from Toke.

7) Add support for fq's Earliest Departure Time to the Host Bandwidth
   Manager (HBM) sample BPF program, from Lawrence.

8) Various cleanups and minor fixes all over the place from many others.

e2c746944e net: ethernet: mediatek: Fix overlapping capability bits.
Both MTK_TRGMII_MT7621_CLK and MTK_PATH_BIT are defined as bit 10.

This can causes issues on non-MT7621 devices which has the
MTK_PATH_BIT(MTK_ETH_PATH_GMAC1_RGMII) and MTK_TRGMII capability set.
The wrong TRGMII setup code can be executed. The current wrongly executed
code doesn’t do any harm on MT7623 and the TRGMII setup for the MT7623
SOC side is done in MT7530 driver So it wasn’t noticed in the test.

Move all capability bits in one enum so that they are all unique and easy
to expand in the future.

Because mtk_eth_path enum is merged in to mkt_eth_capabilities, the
variable path value is no longer between 0 to number of paths,
mtk_eth_path_name can’t be used anymore in this form. Convert the
mtk_eth_path_name array to a function to lookup the pathname.

The old code walked thru the mtk_eth_path enum, which is also merged
with mkt_eth_capabilities. Expand array mtk_eth_muxc so it can store the
name and capability bit of the mux. Convert the code so it can walk thru
the mtk_eth_muxc array.

07a4ddec3c bonding: add an option to specify a delay between peer notifications
Currently, gratuitous ARP/ND packets are sent every `miimon'
milliseconds. This commit allows a user to specify a custom delay
through a new option, `peer_notif_delay'.

Like for `updelay' and `downdelay', this delay should be a multiple of
`miimon' to avoid managing an additional work queue. The configuration
logic is copied from `updelay' and `downdelay'. However, the default
value cannot be set using a module parameter: Netlink or sysfs should
be used to configure this feature.

When setting `miimon' to 100 and `peer_notif_delay' to 500, we can
observe the 500 ms delay is respected:

    20:30:19.354693 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28
    20:30:19.874892 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28
    20:30:20.394919 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28
    20:30:20.914963 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28

In bond_mii_monitor(), I have tried to keep the lock logic readable.
The change is due to the fact we cannot rely on a notification to
lower the value of `bond->send_peer_notif' as `NETDEV_NOTIFY_PEERS' is
only triggered once every N times, while we need to decrement the
counter each time.

iproute2 also needs to be updated to be able to specify this new
attribute through `ip link'.
