NPIV support in freebsd

[bharat singh]

Hi Ken,

root at FCNode1:~ # tail -1 /boot/loader.conf
hint.isp.0.vports=4

root at FCNode1:~ # ctladm port -l
Port Online Type     Name         pp vp WWNN               WWPN

0x2100001b32118e22  4000000  Qlogic  <<<<< no vports enabled after reboot

I tried to add the hint to /boot/device.hints also but still no success.
@Matt any comments ?
