IB/mlx4: Use IBoE (RoCE) IP based GIDs in the port GID table
Currently, the mlx4 driver set IBoE (RoCE) gids to encode related Ethernet netdevice interface MAC address and possibly VLAN id. Change this scheme such that gids encode interface IP addresses (both IP4 and IPv6). This requires learning the IP addresses which are of use by a netdevice associated with the HCA port, formatting them to gids and adding them to the port gid table. Furthermore, events of add and delete address are caught to maintain the gid table accordingly. Associated IP addresses may belong to a master of an Ethernet netdevice on top of that port so this should be considered when building and maintaining the gid table.
