[ofw] ibnetdiscover output: Windows vs. Linux

 Hello,
   Woody noticed in some IB-diags testing that Linux ibnetdiscover outputs a hostname plus the HCA card name where Windows outputs only the HCA card name?
Current speculation is the HCA driver fills in the NodeDescription fields while processing a received NodeRecord Info request MAD?

Do you know why the WIndows driver supplies only the HCA name where the Linux HCA driver supplies the actual hostname (as in output from the hostname cmd) plus the HCA name?

How difficult would it be to correct the Windows HCA drivers to supply the Hostname in addition to the HCA name?

thanks,

stan.
