Hi,

When running the shell application I get following unhandled exception in the EthernetPort class when the NIC is already being used by another BACnet OWS. I currently have Delta Controls enteliWEB connecting over ethernet so it can not bind to that adaptor.

private LibPcapLiveDevice _getCaptureDevice()
{
var devices = LibPcapLiveDeviceList.Instance.Where(dev => dev.Interface != null);

        if(_options.DeviceName != null)
            return devices.Where(dev => dev.Name == _options.DeviceName).FirstOrDefault();
        else
        {
            foreach(var device in devices)
            {
                **if (device.LinkType == PacketDotNet.LinkLayers.Ethernet
                    && device.Interface.MacAddress != null)
                    return device;**
            }

            return null;
        }
    }

An unhandled exception of type 'SharpPcap.DeviceNotReadyException' occurred in SharpPcap.dll

Maybe we should add some error checking to this to handle this common situation.
