Saeed Mahameed says:

====================
mlx5e-updates-2018-08-10

This series provides the following updates to mlx5e netdevice driver.

1) First 4 patches extends the support for ethtool rxnfc flow steering
   - Added ipv6 support
   - l4 proto ip field for both ip6 and ip4

2) Next 4 patches, reorganizing flow steering structures and declaration into
one header file, and add two Kconfig flags to allow disabling/enabling mlx5
netdevice rx flow steering at compile time:
CONFIG_MLX5_EN_ARFS for en_arfs.c
CONFIG_MLX5_EN_RXNFC for en_fs_ehtool.c

3) More kconfig flags dependencies
- vxlan.c depends on CONFIG_VXLAN
- clock.c depends on CONFIG_PTP_1588_CLOCK

4) Reorganize the Makefile
====================
