Subject: [PATCH net-next 00/12] ENETC BD ring cleanup

The highlights of this patch set are:

- Installing a BPF program and changing PTP RX timestamping settings are
  currently implemented through a port reconfiguration procedure which
  triggers an AN restart on the PHY, and these procedures are not
  generally guaranteed to leave the port in a sane state. Patches 9/12
  and 11/12 address that.

- Attempting to put the port down (or trying to reconfigure it) has the
  driver oppose some resistance if it's bombarded with RX traffic
  (it won't go down). Patch 12/12 addresses that.

The other 9 patches are just cleanup in the BD ring setup/teardown code,
which gradually led to bringing the driver in a position where resolving
those 2 issues was possible.

Vladimir Oltean (12):
  net: enetc: set next_to_clean/next_to_use just from
    enetc_setup_txbdr()
  net: enetc: set up RX ring indices from enetc_setup_rxbdr()
  net: enetc: create enetc_dma_free_bdr()
  net: enetc: rx_swbd and tx_swbd are never NULL in
    enetc_free_rxtx_rings()
  net: enetc: drop redundant enetc_free_tx_frame() call from
    enetc_free_txbdr()
  net: enetc: bring "bool extended" to top-level in enetc_open()
  net: enetc: split ring resource allocation from assignment
  net: enetc: move phylink_start/stop out of enetc_start/stop
  net: enetc: implement ring reconfiguration procedure for PTP RX
    timestamping
  net: enetc: rename "xdp" and "dev" in enetc_setup_bpf()
  net: enetc: set up XDP program under enetc_reconfigure()
  net: enetc: prioritize ability to go down over packet processing
