[PATCH v4 00/10] Remove limitations coming from legacy VMDq

[David Marchand <david.marchand@redhat.com>]

Since the commit 88ac4396ad29 ("ethdev: add VMDq support"),
VMDq has been imposing a maximum number of mac addresses in the
mac_addr_add/del API.

Nowadays, new Intel drivers do not support the feature and few other
drivers implement this feature.

This series enforces that the driver announces VMDq pools before
using VMDq related features, then remove the limit of number of
mac addresses for others.

Next step could be to remove the VMDq pool notion from the generic API.
However I have some concern about this, as changing the quite stable
mac_addr_add/del API now seems a lot of noise for not much benefit.

Changes since v3:
- rebased (this series is too late for 26.07),
- update some doxygen comments,
- added mlx5 changes,

Changes since v2:
- changed approach: did not introduce a new device capability,
  relied on already existing dev_info->max_vmdq_pools,
- fixed duplicate mac addition without VMDq,
- updated documentation,

Changes since v1:
- dropped incorrect VMDq feature announce for bnxt representors, em,
  i40e representors, ipn3ke representors,
- fixed buffer overflow on mailbox messages during port restart/VF reset,
- fixed duplicate MAC address installation on port start/restart,

David Marchand (10):
  ethdev: check VMDq availability
  ethdev: skip VMDq pools unless configured
  ethdev: hide VMDq internal sizes
  net/iavf: accept up to 32k unicast MAC addresses
  net/iavf: fix duplicate MAC addresses install
  net/mlx5: remove MAC addresses flush helper on Linux
  net/mlx5: remove redundant MAC address index checks
  net/mlx5: pass maximum number of unicast MAC to common code
  net/mlx5: use bitset for tracking MAC addresses
  net/mlx5: accept more unicast MAC addresses
