[PATCH net-next v2 0/7] net: xilinx: axienet: Add 10G/25G (XXV) ethernet support

[Suraj Gupta]

This patch series extends the AXI Ethernet driver to support the
XXV Ethernet subsystem.

- Add a devm_clk_bulk_get_enable() helper for consumers that need a set
  of mandatory clocks enabled with device-managed cleanup.

- Refactor through struct axienet_config so per-MAC behaviour is
  expressed as capability flags and callbacks instead of runtime
  MAC-type checks in the shared code.

- Document the XXV IP in Devicetree.

- Add support for the XXV Ethernet subsystem.

- Add a preparatory RMON cleanup, a statistics-ops refactor of
  struct axienet_config, and ethtool / ndo_get_stats64 counter reporting
  for XXV.

Notes:
- This series depends on [1], which is sent as part of another series.
  That change is required for this series to compile and is not included
  here to avoid duplication.
- "xlnx,rxmem" is a required property; driver changes for that are
  handled in a separate patch series[2].
- Due to phylink limitations, we aren't able to advertise both 10G and
  25G base-r interfaces and switch between them using ethtool.
  We are open to suggestions on how to handle this.

Changes in v2:
- Patch 1/7:
  * Add Reviewed-by: Brian Masney <bmasney@xxxxxxxxxx>. Thanks Brian!
- Patch 3/7:
  * Split the XXV binding into its own schema file
    (xlnx,xxv-ethernet.yaml) instead of extending xlnx,axi-ethernet.yaml
    with if/then branches, per Rob Herring's review.
  * Add a multichannel (MCDMA) example.
- Patch 4/7:
  * Require both GT Wizard reset-done bits in axienet_xxv_poll_link_ready()
    so polling does not exit before both the TX and RX resets complete.
