[pull request][net-next V2 00/12] Mellanox, mlx5e updates 2018-07-18

[Saeed Mahameed <saeedm@mellanox.com>]

Hi Dave,

This series includes updates for mlx5e net device driver, with a couple
of major features and some misc updates.

Please notice the mlx5-next merge patch at the beginning:
"Merge branch 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux"

For more information please see tag log below.

Please pull and let me know if there's any problem.

v1->v2:
- Dropped "Support PCIe buffer congestion handling via Devlink" patches until the
comments are addressed.

Thanks,
Saeed.

  net/mlx5e: Use PARTIAL_GSO for UDP segmentation (2018-07-23 15:01:11 -0700)

----------------------------------------------------------------
mlx5e-updates-2018-07-18

This series includes update for mlx5e net device driver.

1) From Feras Daoud, Added the support for firmware log tracing,
first by introducing the firmware API needed for the task and then
For each PF do the following:
    1- Allocate memory for the tracer strings database and read it from the FW to the SW.
    2- Allocate and dma map tracer buffers.

    Traces that will be written into the buffer will be parsed as a group
    of one or more traces, referred to as trace message. The trace message
    represents a C-like printf string.
Once a new trace is available  FW will generate an event indicates new trace/s are
available and the driver will parse them and dump them using tracepoints
event tracing

Enable mlx5 fw tracing by:
echo 1 > /sys/kernel/debug/tracing/events/mlx5/mlx5_fw/enable

Read traces by:
cat /sys/kernel/debug/tracing/trace

2) From Roi Dayan, Remove redundant WARN when we cannot find neigh entry

3) From Jianbo Liu, TC double vlan support
- Support offloading tc double vlan headers match
- Support offloading double vlan push/pop tc actions

4) From Boris, re-visit UDP GSO, remove the splitting of UDP_GSO_L4 packets
in the driver, and exposes UDP_GSO_L4 as a PARTIAL_GSO feature.
