[PATCH net-next v5 0/8] octeon_ep: deferred probe and mailbox

[Veerasenareddy Burru]

Implement Deferred probe, mailbox enhancements and heartbeat monitor.

v4 -> v5:
   - addressed review comments
     https://lore.kernel.org/all/20230323104703.GD36557@unreal/
     replaced atomic_inc() + atomic_read() with atomic_inc_return().

v3 -> v4:
   - addressed review comments on v3
     https://lore.kernel.org/all/20230214051422.13705-1-vburru@xxxxxxxxxxx/
   - 0004-xxx.patch v3 is split into 0004-xxx.patch and 0005-xxx.patch
     in v4.
   - API changes to accept function ID are moved to 0005-xxx.patch.
   - fixed rct violations.
   - reverted newly added changes that do not yet have use cases.

v2 -> v3:
   - removed SRIOV VF support changes from v2, as new drivers which use
     ndo_get_vf_xxx() and ndo_set_vf_xxx() are not accepted.
     https://lore.kernel.org/all/20221207200204.6819575a@xxxxxxxxxx/

     Will implement VF representors and submit again.
   - 0007-xxx.patch and 0008-xxx.patch from v2 are removed and
     0009-xxx.patch in v2 is now 0007-xxx.patch in v3.
   - accordingly, changed title for cover letter.

v1 -> v2:
   - remove separate workqueue task to wait for firmware ready.
     instead defer probe when firmware is not ready.
     Reported-by: Leon Romanovsky <leon@xxxxxxxxxx>
   - This change has resulted in update of 0001-xxx.patch and
     all other patches in the patchset.
