> Subject: [PATCH V4 2/2] net/mlx5: add support for flows targeting multicast
> MAC addresses
>
> Device multicast MAC addresses are managed using the mac_addr_add and
> mac_addr_remove APIs.
>
> In the mlx5_dev_spawn function, devices such as PF, VFs, and SFs obtain the
> MAC addresses configured in netdev via netlink and store them in the PMD
> device data, which also includes multicast MAC addresses. Default rules are
> created for each MAC address to filter traffic accordingly.
>
> Previously, multicast MAC address flows were mistakenly disabled, which
> caused mac_addr_add to stop functioning for multicast MAC addresses,
> resulting in missed multicast traffic.
>
> To address this, default rules for multicast MAC addresses created by PMD
> should now be set up within mlx5_traffic_enable to properly update and
> manage multicast MAC address rules.
>
> Fixes: 2d0665a7f771 ("net/mlx5: align PF and VF/SF MAC address handling")
