isp(4) WWPN

[Ivan Voras]

I'm trying to find out the port names on the isp controller, and the the
isp(4) page says:

SYSCTL OPTIONS
...
     dev.isp.N.wwnn
             This is the readonly World Wide Node Name value for this port.

     dev.isp.N.wwpn
             This is the readonly World Wide Port Name value for this port.

However, this looks unimplemented:

~# sysctl dev.isp
dev.isp.0.%desc: Qlogic ISP 2432 PCI FC-AL Adapter
dev.isp.0.%driver: isp
dev.isp.0.%location: slot=0 function=0 handle=\_SB_.PCI0.PT06.PES2
dev.isp.0.%pnpinfo: vendor=0x1077 device=0x2432 subvendor=0x103c
subdevice=0x1705 class=0x0c0400
dev.isp.0.%parent: pci19
dev.isp.1.%desc: Qlogic ISP 2432 PCI FC-AL Adapter
dev.isp.1.%driver: isp
dev.isp.1.%location: slot=0 function=1 handle=\_SB_.PCI0.PT06.PE21
dev.isp.1.%pnpinfo: vendor=0x1077 device=0x2432 subvendor=0x103c
subdevice=0x1705 class=0x0c0400
dev.isp.1.%parent: pci19

~# sysctl dev.isp.0.wwpn
sysctl: unknown oid 'dev.isp.0.wwpn'

Any ideas how to work around it?

This is 8-stable amd64.
