Changes in v4:
- Rebased on net-next.
- Link to v3: https://lore.kernel.org/r/20260813-stmmac-rx-fifo-block-v3-0-738acbee55d9@gmail.com

Changes in v3:
- v2 tried to fix the ordering in teardown path, but it still would
  not follow the ideal flow mentioned in the databook. So have
  seperated the patches to deal with the teardown and some findings
  from sashiko.

- "net: stmmac: enable MAC rx/tx after DMA start": reduced in scope,
  now only moves the MAC enable after stmmac_start_all_dma() in
  stmmac_hw_setup() and stmmac_xdp_open().
  This is to handle the overflow scenario during bootup causing hang.
  The teardown side in __stmmac_release() is no longer touched here.
  This change could go independently fix the overflow hang at bootup.

- Added "net: stmmac: xgmac: tear the datapath down in the documented
  order": for ensuring ordered sequence is followed for teardown.

- Added "net: stmmac: xgmac: decouple the MAC Rx/Tx enables from the
  DMA ops": drops the global TE/RE writes from the per-channel XGMAC
  DMA start/stop ops.

- Link to v2: https://lore.kernel.org/r/20260727-stmmac-rx-fifo-block-v2-1-4dc3457d31d0@gmail.com

Changes in v2:
- Corrected the ordering in teardown for xdp at stmmac_xdp_release().
- Link to v1: https://lore.kernel.org/r/20260726-stmmac-rx-fifo-block-v1-1-45ab094b6c02@gmail.com
