This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. Gordan, I do not believe you are correct in stating the ref count should reflect the number of interfaces configured. My understanding is that because network devices need to be hot plugged, the ref count purposely remains at zero. I would suggest that you check the ref count on an out-of-box drivers from the specific vendors for the drivers you referenced (tg3, e1000, sky2) if you want to make a true comparison, rather than comparing them to sk98lin. Apples to apples, so to speak. Perhaps, sk98lin has it wrong and this is not due to the fact it is an external kernel module. It would appear you are right. I just checked on a vanilla kernel.org kernel, and NIC driver ref counts are 0 on those, too. Okay, thanks for checking. I suppose what would appear to be intuitive on face value is not that way it is when you take in all the variables, such as how to deal with hotplug as in this case. I will close this bz as NOTABUG. |
