In specific language, VB NET you have Mycomputer.network , after you
have wmi (not yet for mono/linux) where you can loop for each eth
device and know lot of info.
I really think, the best of Mono is the "easy" crossplatform, then
take lot of platform specific solution are not the best choice ?

In C# :


			IPGlobalProperties computerProperties =
IPGlobalProperties.GetIPGlobalProperties();

			NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();

			Trace.WriteLine(System.DateTime.Now + ": " + "Interface information
for " + computerProperties.HostName + "." +
computerProperties.DomainName);

			NetworkInterface adapter = null;

			string[] Tablo = null;

			int Compteur = 0;

			bool IsUp = false;

			foreach (NetworkInterface adapter_loopVariable in nics) {

				adapter = adapter_loopVariable;

				if (adapter.OperationalStatus == OperationalStatus.Up &
adapter.NetworkInterfaceType != NetworkInterfaceType.Loopback) IsUp =
true;

				IPInterfaceProperties properties = adapter.GetIPProperties();

				//Trace.WriteLine(Date.Now & ": " & adapter.Description)

				//Trace.WriteLine(Date.Now & ": " &
String.Empty.PadLeft(adapter.Description.Length, "="c))

				//Trace.WriteLine(Date.Now & ": " & "  Interface type
.......................... : {0}", adapter.NetworkInterfaceType)
'Ethernet

				//Trace.WriteLine(Date.Now & ": " & "  Physical Address
........................ : {0}",
adapter.GetPhysicalAddress().ToString())

				//Trace.WriteLine(Date.Now & ": " & "  Is receive
only.......................... : {0}", adapter.IsReceiveOnly)

				//Trace.WriteLine(Date.Now & ": " & "
Multicast................................ : {0}",
adapter.SupportsMulticast)

				if (adapter.GetPhysicalAddress().ToString() != string.Empty) {

					//And adapter.OperationalStatus = OperationalStatus.Up Then

					Array.Resize(ref Tablo, Compteur + 1);

					Tablo[Compteur] = adapter.GetPhysicalAddress().ToString();

					Compteur += 1;

				}

			}

			if (IsUp == false) {

				MessageBox.Show("Aucune carte rÃ(c)seaux detectÃ(c)e et/ou
conectÃ(c)e, impossible de continuer !", "Fatal",
MessageBoxButtons.OK, MessageBoxIcon.Exclamation);

				//End

			}


In VB NET :

        Dim adapter As NetworkInterface
        Dim Tablo() As String = Nothing
        Dim Compteur As Integer = 0
        Dim IsUp As Boolean = False
        For Each adapter In nics
            If adapter.OperationalStatus = OperationalStatus.Up And _
            adapter.NetworkInterfaceType <>
NetworkInterfaceType.Loopback Then IsUp = True
            Dim properties As IPInterfaceProperties = adapter.GetIPProperties()

                Tablo(Compteur) = adapter.GetPhysicalAddress().ToString()
                Compteur += 1
            End If
        Next adapter
        If IsUp = False Then
            MessageBox.Show("Aucune carte réseaux detectée et/ou
conectée, impossible de continuer !", _
            "Fatal", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
            'End
        End If
