If all bits in this object are disabled, and auto-negotiation is enabled on the port, then the physical link process on the port will be disabled. Any change in the value of this bit map will force the PHY to restart the auto-negotiation process. This will have the same effect as physically unplugging and reattaching the cable plant attached to this port. Only capabilities present in the hardware as indicated by bnIfExtnExtHwAdvCapability can be advertised. The default value for this object will be the value of the associated instance of bnIfExtnExtHwAdvCapability.
