xsos --lspci showing 2 1.5-port (3) QLogic Corp... or 3 3.33333-port NICs

This is really common:

[rsaw:tmp]$ cat fc
03:00.0 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 03)
03:00.1 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 03)                                                                                                       
08:00.0 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 03)
[rsaw:tmp]$ xsos --L fc
LSPCI
  Net/Storage:

This, not as much:

The problem with the second system is that it has three cards that identify exactly the same ... except for the fact that two of them are 4-port cards, and one of them is a 2-port card. xsos assumes that if cards identify the same ... that they'll have the same number of ports.

Yikes.

The fibre channel situation certainly appears similar from the lspci output, but I have no hands-on experience with these systems ... it's so common that it makes me wonder if it really is a 2-port card that identifies the same as a 1-port card.

Here's the code from LSPCI():

  awk -vH_IMP="${c[Imp]}" -vH2="${c[H2]}" -vH0="${c[0]}" '
    /Ethernet controller:|Network controller:|Fibre Channel:|Mass storage controller:|InfiniBand:/ {
      # Save 
      split($1, slot, ":")
      $1 = ""
      sub(" ", "")
      split($0, type, ":")
      dev[type[2]] ++
      if (!(slot[1] SUBSEP type[2] in slots)) {
        slots[slot[1], type[2]]
        slotcount[type[2]] ++
      }
    }
    END {
      printf "%s  Net/Storage:%s\n", H2, H0
      for (devtype in dev) {
        slotc = slotcount[devtype]
        typec = dev[devtype]
        ports = ""
        if (typec > 1) {
          numports = typec/slotc
          if      (numports == 1) numports = "single"
          else if (numports == 2) numports = "dual"
          else if (numports == 3) numports = "triple"
          else if (numports == 4) numports = "quad"
          ports = " "slotc " " numports "-port"
        }
        printf "   %s%s (%s)%s%s\n", H_IMP, ports, typec, H0, devtype
      }
    }
  ' <<<"$lspci_input"
