Subject: [PATCH net-next V1 00/12] Mellanox 100G ethernet SRIOV Upgrades

Hi Dave,

This series introduces new features and upgrades for mlx5 etherenet SRIOV,
while the first patch provides a bug fixes for a compilation issue introduced 
buy the previous aRFS series for when CONFIG_RFS_ACCEL=y and CONFIG_MLX5_CORE_EN=n.

Changes from V0:
    - 1st patch: Don't add a new Kconfig flag.  Instead, compile out en_arfs.c contents when CONFIG_RFS_ACCEL=n

SRIOV upgrades:
    - Use synchronize_irq instead of the vport events spin_lock
    - Fix memory leak in error flow
    - Added full VST support
    - Spoofcheck support
    - Trusted VF promiscuous and allmulti support

VST and Spoofcheck in details:
    - Adding Low level firmware commands support for creating ACLs
     (Access Control Lists) Flow tables.  ACLs are regular flow tables with 
     the only exception that they are bound to a specific e-Switch vport (VF)
     and they can be one of two types 
        > egress ACL: filters traffic going from e-Switch to VF.
        > ingress ACL: filters traffic going from VF to e-Switch.
    - Ingress/Egress ACLs (per vport) for VF VST mode filtering.
    - Ingress/Egress ACLs (per vport) for VF spoofcheck filtering.
    - Ingress/Egress ACLs (per vport) configuration:
        > Created only when at least one of (VST, spoofcheck) is configured.
	> if (!spoofchk && !vst) allow all traffic.  i.e. no ACLs.
        > if (spoofchk && vst) allow only untagged traffic with smac=original mac sent from the VF.
        > if (spoofchk && !vst) allow only traffic with smac=original mac sent from the VF.
        > if (!spoofchk && vst) allow only untagged traffic.

Trusted VF promiscuous and allmulti support in details:
    - Added two flow groups for allmulti and promisc VFs to the e-Switch FDB table
        > Allmulti group: One rule that forwards any mcast traffic coming from
                          either uplink or VFs/PF vports.
        > Promisc group: One rule that forwards all unmatched traffic coming from uplink.
    - Add vport context change event handling for promisc and allmulti
      If VF is trusted respect the request and:
        > if allmulti request: add the vport to the allmulti group.
          and to all other L2 mcast address in the FDB table.
        > if promisc request: add the vport to the promisc group.
        > Note: A promisc VF can only see traffic that was not explicitly matched to 
                or requested by any other VF.
