Can we have some common wording on how to describe the topology?
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?
