> Subject: [PATCH] net/mlx5: align PF and VF/SF MAC addresses handling
>
> In the mlx5_dev_spawn function, the Virtual Function (VF) synchronizes
> MAC addresses from the kernel using netlink. It queries the netdev-
> configured MACs and populates the list in the PMD device data, including
> multicast MAC addresses. These addresses are later used for control flow
> creation, allowing traffic for the listed MACs to be received. However, the
> Physical Function (PF) does not synchronize with the kernel and thus does
> not add any multicast MAC address rules when enabling traffic. This
> discrepancy causes the IFF_ALLMULTI ioctl code to malfunction, as it fails to
> disable all multicast traffic, leaving the VF still able to see it.
>
> To align PF and VF behavior, only unicast MAC address flows should be
> added.
