[dpdk-dev] [PATCH v4 0/3] net/mlx5: use Netlink in VF mode

[Nelio Laranjeiro <nelio.laranjeiro@6wind.com>]

When MLX5 behaves in VF mode and the hypervisor have **trusted** this VF, to
be able to receive specific traffic some requests must be done to configure
the NIC.  There is no API currently available to do it though Verbs, but there
is in Linux side using Netlink.

The specific cases are:
- Enable/disable promiscuous mode.
- Enable/disable allmulti mode.
- Add/remove mac addresses.

Changes in v4:

Track MAC addresses added by the PMD and not present in the bridge table to
remove them when leaving.

Changes in v3:

Add missing room to add the MAC address in the Netlink message.

Changes in v2:

Embed Netlink socket communication inside the PMD.

Nelio Laranjeiro (3):
  net/mlx5: use Netlink to add/remove MAC addresses
  net/mlx5: use Netlink to enable promisc / allmulti mode
  net/mlx5: add a parameter for Netlink support in VF
