7edcb8ecbe mlxsw: spectrum_switchdev: Schedule respin during trans prepare
Since there's no special support for the bridge events, the driver
returns -EOPNOTSUPP, and thus the commit never happens. Therefore
schedule respin during the prepare stage: there's no real difference one
way or another.

This fixes the problem that mirror-to-gretap offload wouldn't adapt to
changes in bridge vlan configuration right away and another notification
would have to arrive for mlxsw to catch up.

2855118fda rocker: rocker_main: Ignore bridge VLAN events
A follow-up patch enables emitting VLAN notifications for the bridge CPU
port in addition to the existing slave port notifications. These
notifications have orig_dev set to the bridge in question.

Because there's no specific support for these VLANs, just ignore the
notifications to maintain the current behavior.

3ded9f2b35 net: ethernet: freescale: fix false-positive string overflow warning
While compile-testing on arm64 with gcc-8.1, I ran into a build diagnostic:

drivers/net/ethernet/freescale/fec_main.c: In function 'fec_probe':
drivers/net/ethernet/freescale/fec_main.c:3517:25: error: '%d' directive writing between 1 and 10 bytes into a region of size 5 [-Werror=format-overflow=]

   sprintf(irq_name, "int%d", i);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It appears this has never shown on ppc32 or arm32 for an unknown reason, but
now gcc fails to identify that the 'irq_cnt' loop index has an upper bound
of 3, and instead uses a bogus range.

To work around the warning, this changes the sprintf to snprintf with the
correct buffer length.

f3a52c6162 mlxsw: pci: Utilize MRSR register to perform FW reset
So far, the PCI BAR0 register is used for triggering FW reset. However,
that is a legacy attitude and it is recommended to use MRSR to perform
reset instead. So do that. Move the reset into init() function as
the cmd interface needs to be used. With that, IRQ initialization needs
to be moved as well. As a side effect, the reset move simplifies
the devlink reload flow.

47bf9df2e8 mlxsw: spectrum: Forbid creation of VLAN 1 over port/LAG
VLAN 1 is internally used for untagged traffic. Prevent creation of
explicit netdevice for that VLAN, because that currently isn't supported
and leads to the NULL pointer dereference cited below.

Fix by preventing creation of VLAN devices with VID of 1 over mlxsw
devices or LAG devices that involve mlxsw devices.

Saeed Mahameed says:

====================
mlx5e-updates-2018-05-25

This series includes updates for mlx5e netdev driver.

1) Allowr flow based VF vport mirroring under sriov switchdev scheme,
added support for offloading the TC mirred mirror sub-action, from
Chris Mi.

=================
From: Or Gerlitz <ogerlitz@mellanox.com>

The user will typically set the actions order such that the mirror
port (mirror VF) sees packets as the original port (VF under
mirroring) sent them or as it will receive them. In the general case,
it means that packets are potentially sent to the mirror port before
or after some actions were applied on them.

To properly do that, we follow on the exact action order as set for
the flow and make sure this will also be the case when we program the
HW offload.

If all the actions should apply before forwarding to the mirror and dest port,
mirroring is just multicasting to the two vports. Otherwise, we split
the TC flow to two HW rules, where the 1st applies only the actions
needed up to the mirror (if there are such) and the 2nd the rest of
the actions plus the forwarding to the dest vport.

16b496fd90 net: hns3: Remove unused led control code
In the previous implementation of led control for fibre port , parses the
port speed configuration, checks the link status and traffic status per
second, and updates the blink status of link led, traffic led and speed
led.

Now, the firmware takes responsibility to handle the led, the dirver just
needs to deal with locate command.

So the codes for link led, traffic led and speed led are useless now. This
patch removes these redundant codes.

When we down the port, some packets are left in TX/RX buffer. When we
up the port again, these old packets are forwarded to protocol stack
or are sent to internet. It will make some problem. TX/RX buffer should
be cleared when stopping port. This patch adds some function to ensure
the buffer is clean when port is started. We should clear the rings
when clients are being un-initialized as well.

3125642695 net: netsec: reduce DMA mask to 40 bits
The netsec network controller IP can drive 64 address bits for DMA, and
the DMA mask is set accordingly in the driver. However, the SynQuacer
SoC, which is the only silicon incorporating this IP at the moment,
integrates this IP in a manner that leaves address bits [63:40]
unconnected.

Up until now, this has not resulted in any problems, given that the DDR
controller doesn't decode those bits to begin with. However, recent
firmware updates for platforms incorporating this SoC allow the IOMMU
to be enabled, which does decode address bits [47:40], and allocates
top down from the IOVA space, producing DMA addresses that have bits
set that have been left unconnected.

Both the DT and ACPI (IORT) descriptions of the platform take this into
account, and only describe a DMA address space of 40 bits (using either
dma-ranges DT properties, or DMA address limits in IORT named component
nodes). However, even though our IOMMU and bus layers may take such
limitations into account by setting a narrower DMA mask when creating
the platform device, the netsec probe() entrypoint follows the common
practice of setting the DMA mask uncondionally, according to the
capabilities of the IP block itself rather than to its integration into
the chip.

It is currently unclear what the correct fix is here. We could hack around
it by only setting the DMA mask if it deviates from its default value of
DMA_BIT_MASK(32). However, this makes it impossible for the bus layer to
use DMA_BIT_MASK(32) as the bus limit, and so it appears that a more
comprehensive approach is required to take DMA limits imposed by the
SoC as a whole into account.

In the mean time, let's limit the DMA mask to 40 bits. Given that there
is currently only one SoC that incorporates this IP, this is a reasonable
approach that can be backported to -stable and buys us some time to come
up with a proper fix going forward.
