Subject: [PATCH net v4 0/3] disable interrupts and ensure dbell updation

Disable per ring interrupts when netdev goes down and ensure dbell BADDR
updation for both PFs and VFs by adding wait and check for updated value.

Resending based on discussion with reviewer. 

Vimlesh Kumar (3):
  octeon_ep: disable per ring interrupts
  octeon_ep: ensure dbell BADDR updation
  octeon_ep_vf: ensure dbell BADDR updation

V4:
- Remove unnecessary brackets.
- Add a new label to handle oq setup error case properly.

V3:
- previous discussion: https://lore.kernel.org/all/20260107131857.3434352-1-vimleshk@marvell.com/
- Use reverse christmas tree order variable declaration.
- Return error if timeout happens during setup oq.
