Hi Dave,

This series from Gal and Saeed provides updates to mlx5 vxlan implementation.

For more information please see tag log below.

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

V1->V2:
 - Drop the rw lock patch.

Thanks,
Saeed.

  net/mlx5e: Issue direct lookup on vxlan ports by vport representors (2018-07-27 15:46:13 -0700)

----------------------------------------------------------------
mlx5e-updates-2018-07-27 (Vxlan updates)

This series from Gal and Saeed provides updates to mlx5 vxlan implementation.

Gal, started with three cleanups to reflect the actual hardware vxlan state
- reflect 4789 UDP port default addition to software database
- check maximum number of vxlan  UDP ports
- cleanup an unused member in vxlan work

Then Gal provides performance optimization by replacing the
vxlan radix tree with a hash table.

Measuring mlx5e_vxlan_lookup_port execution time:

                      Radix Tree   Hash Table
     --------------- ------------ ------------
      Single Stream   161 ns       79  ns (51% improvement)
      Multi Stream    259 ns       136 ns (47% improvement)

    Measuring UDP stream packet rate, single fully utilized TX core:
    Radix Tree: 498,300 PPS
    Hash Table: 555,468 PPS (11% improvement)

Next, from Saeed, vxlan refactoring to allow sharing the vxlan table
between different mlx5 netdevice instances like PF and VF representors,
this is done by making mlx5 vxlan interface more generic and decoupling
it from PF netdevice structures and logic, then moving it into mlx5 core
as a low level interface so it can be used by VF representors, which is
illustrated in the last patch of the serious.

-Saeed.
