[PATCH net-next v3 7/12] net: atlantic: implement AQC113 L2/L3/L4 RX filter ops

[<sukhdeeps@marvell.com>]

From: Sukhdeep Singh <sukhdeeps@marvell.com>

Implement complete RX filter management for AQC113 hardware:

- Add tag-based filter policy with reference-counted sharing
  (hw_atl2_filter_tag_get/put), allowing multiple filter rules to share
  the same L3 or L4 hardware filter when their match criteria are
  identical.

- Implement L3 (IPv4/IPv6 source/destination address and protocol)
  filter find, get (program HW and increment refcount), and put
  (decrement refcount and clear HW when last user releases).

- Implement L4 (TCP/UDP/SCTP source/destination port) filter management
  with the same find/get/put pattern.

- Add combined L3L4 filter configuration (hw_atl2_new_fl3l4_configure)
  that translates legacy aq_rx_filter_l3l4 commands into AQC113 separate
  L3+L4 filter programming with Action Resolver Table (ART) entries.

- Add L2 ethertype filter set/clear (hw_atl2_hw_fl2_set/clear) with
  tag-based ART integration.

- Wire .hw_filter_l2_set, .hw_filter_l2_clear, .hw_filter_l3l4_set
  into hw_atl2_ops.
