> As the internal MAC table is divided into Unicast and Multicast address
> sections, we should check the type of synched MAC address before storing
> it to the internal table. Currently the check is not done, and the
> synched MAC of 33:33:00:00:00:01 gets stored in the unicast section
> (mostly index 1) causing all subsequent mlx5_set_mc_addr_list()
> to fail with error -EADDRINUSE, as the mac_list contains the MAC
> 33:33:00:00:00:01. This denies adding of any new multicast address to
> the internal list and also fails to add the MAC address to the device
> in case of SR-IOV VF.
