This patch on the Marvell PPv2 driver is only cosmetic. Two typos are
removed as well as other cosmetic fixes, such as extra new lines or tabs

mlx5e-updates-2018-05-17
From: Or Gerlitz <ogerlitz@mellanox.com>
This series addresses a regression introduced by the
shared block TC changes [1]. Currently, for VF->VF and uplink->VF rules, the
TC core (cls_api) attempts to offload the same flow multiple times into
the driver, as a side effect of the mlx5 registration to the egdev callback.
We use the flow cookie to ignore attempts to add such flows, we can't
reject them (return error), b/c this will fail the offload attempt, so we
ignore that.
The last patch of the series deals with exposing HW stats counters through
ethtool for the vport reps.
Dave - the regression that we are addressing was introduced in 4.15 [1] and applies
to nfp and mlx5. Jiri suggested to push driver side fixes to net-next, this is
already done for nfp [2][3]. Once this is upstream, we will submit a small/point
single patch fix for the TC core code which can serve for net and stable, but not
carried into net-next, b/c it might limit some future use-cases.
[1] 208c0f4b5237 "net: sched: use tc_setup_cb_call to call per-block callbacks"
[2] c50647d "nfp: flower: ignore duplicate cb requests for same rule"

mlx5-updates-2018-05-17
mlx5 core dirver updates for both net-next and rdma-next branches.
From Christophe JAILLET, first three patche to use kvfree where needed.
From: Or Gerlitz <ogerlitz@mellanox.com>
Next six patches from Roi and Co adds support for merged
sriov e-switch which comes to serve cases where both PFs, VFs set
on them and both uplinks are to be used in single v-switch SW model.
When merged e-switch is supported, the per-port e-switch is logically
merged into one e-switch that spans both physical ports and all the VFs.
This model allows to offload TC eswitch rules between VFs belonging
to different PFs (and hence have different eswitch affinity), it also
sets the some of the foundations needed for uplink LAG support.

Currently, each representor netdev use their own hash table to keep
the mapping from TC flow (f->cookie) to the driver offloaded instance.
The table is the one which originally was added for offloading TC NIC
(not eswitch) rules.
This scheme breaks when the core TC code calls us to add the same flow
twice, (e.g under egdev use case) since we don't spot that and offload
a 2nd flow into the HW with the wrong source vport.
As a pre-step to solve that, we move to use a single table which keeps
all offloaded TC eswitch flows. The table is located at the eswitch
uplink representor object.

device) mechanism, we treat this as egress, all other cases (NIC
and e-switch) are considred ingress.
This is preparation step that will allow us to identify "wrong"

This patch makes use of build_skb() throughout in driver's receieve
data path [HW gro flow and non HW gro flow]. With this, driver can
build skb directly from the page segments which are already mapped
to the hardware instead of allocating new SKB via netdev_alloc_skb()
and memcpy the data which is quite costly.
This really improves performance (keeping same or slight gain in rx
throughput) in terms of CPU utilization which is significantly reduced
[almost half] in non HW gro flow where for every incoming MTU sized
packet driver had to allocate skb, memcpy headers etc. Additionally
in that flow, it also gets rid of bunch of additional overheads
[eth_get_headlen() etc.] to split headers and data in the skb.
Tested with:
system: 2 sockets, 4 cores per socket, hyperthreading, 2x4x2=16 cores

10GbE Intel Wired LAN Driver Updates 2018-05-17
This series contains updates to ixgbe, ixgbevf and ice drivers.
Cathy Zhou resolves sparse warnings by using the force attribute.
Mauro S M Rodrigues fixes a bug where IRQs were not freed if a PCI error
recovery system opts to remove the device which causes
ixgbe_io_error_detected() to return PCI_ERS_RESULT_DISCONNECT before
calling ixgbe_close_suspend() which results in IRQs not freed and
crashing when the remove handler calls pci_disable_device(). Resolved
this by calling ixgbe_close_suspend() before evaluating the PCI channel
state.
Pavel Tatashin releases the rtnl_lock during the call to
ixgbe_close_suspend() to allow scaling if device_shutdown() is
multi-threaded.
Emil modifies ixgbe to not validate the MAC address during a reset,
unless the MAC was set on the host so that the VF will get a new MAC
address every time it reloads. Also updates ixgbevf to set
hw->mac.perm_addr in order to retain the custom MAC on a reset.
Anirudh updates the ice NVM read/erase/update AQ commands to align with
the latest specification.

Convert the PPv2 driver to implement phylink helpers, and use phylink in
DT mode. The other mode supported is ACPI, which will need further work
in order to be entirely compatible with phylink.
The MAC and GoP configuration functions were completely moved to fit
into the phylink helpers. When a PHY is always present between the MAC
and the physical port, phylink only is used, but when this is not the
case (the MAC directly is connected to the physical port) the link IRQ
is used to detect changes in the link state and call phylink_mac_change.
The ACPI mode do not uses phylink as of now, and the changes shouldn't
impact its use.

The early versions of am33xx devices, related to ES1.0 SoC revision
have errata limiting mq support. That's the same errata as
commit 7da1160002f1 ("drivers: net: cpsw: add am335x errata workarround for
interrutps")
AM33xx Errata [1] Advisory 1.0.9
http://www.ti.com/lit/er/sprz360f/sprz360f.pdf
After additional investigation were found that drivers w/a is
propagated on all AM33xx SoCs and on DM814x. But the errata exists
only for ES1.0 of AM33xx family, limiting mq support for revisions
after ES1.0. So, disable mq support only for related SoCs and use
separate polls for revisions allowing mq.

Set hw->mac.perm_addr in ixgbevf_set_mac() in order to avoid losing the
custom MAC on reset. This can happen in the following case:
>ip link set $vf address $mac
>ethtool -r $vf

Do not validate the MAC address during a reset, unless the MAC was set on
the host. This way the VF will get a new MAC address every time it reloads.
Remove the "no MAC address assigned" message since it will get spammed on
reset and it doesn't help much as the MAC on the VF is randomly generated.

Currently, during device_shutdown() ixgbe holds rtnl_lock for the duration
of lengthy ixgbe_close_suspend(). On machines with multiple ixgbe cards
this lock prevents scaling if device_shutdown() function is multi-threaded.
It is not necessary to hold this lock during ixgbe_close_suspend()
as it is not held when ixgbe_close() is called also during shutdown but for
kexec case.
