net/mlx5e: Fix multicast counter not up-to-date in "ip -s"
Currently the FW does not generate events for counters other than error counters. Unlike ".get_ethtool_stats", ".ndo_get_stats64" (which ip -s uses) might run in atomic context, while the FW interface is non atomic. Thus, 'ip' is not allowed to issue FW commands, so it will only display cached counters in the driver. Add a SW counter (mcast_packets) in the driver to count rx multicast packets. The counter also counts broadcast packets, as we consider it a special case of multicast. Use the counter value when calling "ip -s"/"ifconfig".
