In sli4_init_link we have 'F_P2P' and 'F_FCAL'. In sli4_read_cfg_type we have 'TOPO_FC_DA' and 'TOPO_FC_AL'. Here we have 'TOPOLOGY_NPORT' and 'TOPOLOGY_FC_AL'. So is 'P2P' identical to 'DA'? Or are these different? And is 'DA' (which presumeably stands for 'direct attach') the _actual_ direct attach (ie no switch present), or does a connection to a switch also count as 'direct attach'? And what about 'NPort'; I was under the impression that nport was a port type, not a topology. Can we please have some common naming scheme (and possibly a short comment what this actually is) to avoid the confusion here? > +enum sli4_read_topo_speed { > + SLI4_READ_TOPOLOGY_SPEED_NONE = 0x00, > + SLI4_READ_TOPOLOGY_SPEED_1G = 0x04, > + SLI4_READ_TOPOLOGY_SPEED_2G = 0x08, > + SLI4_READ_TOPOLOGY_SPEED_4G = 0x10, > + SLI4_READ_TOPOLOGY_SPEED_8G = 0x20, > + SLI4_READ_TOPOLOGY_SPEED_10G = 0x40, > + SLI4_READ_TOPOLOGY_SPEED_16G = 0x80, > + SLI4_READ_TOPOLOGY_SPEED_32G = 0x90, > +};
