Subject: [PATCH net-next 0/2] Marvell Prestera add flower and match all support

From: Vadym Kochan <vkochan@...vell.com>

Add ACL infrastructure for Prestera Switch ASICs family devices to
offload cls_flower rules to be processed in the HW.

ACL implementation is based on tc filter api. The flower classifier
is supported to configure ACL rules/matches/action.

Supported actions:

    - drop
    - trap
    - pass

Supported dissector keys:

    - indev
    - src_mac
    - dst_mac
    - src_ip
    - dst_ip
    - ip_proto
    - src_port
    - dst_port
    - vlan_id
    - vlan_ethtype
    - icmp type/code

- Introduce matchall filter support
- Add SPAN API to configure port mirroring.
- Add tc mirror action.

At this moment, only mirror (egress) action is supported.

Example:
    tc filter ... action mirred egress mirror dev DEV
