+	  The fcst kernel module implements an SCST target driver for the FCoE
+	  protocol. FCoE or Fibre Channel over Ethernet is a protocol that
+	  allows to communicate fibre channel frames over an Ethernet
+	  network. Since the FCoE protocol requires a lossless Ethernet
+	  network, special network adapters and switches are required.
+	  Ethernet network adapters that support FCoE are called Converged
+	  Network Adapters (CNA). The standard that makes lossless Ethernet
+	  communication possible is called DCB or Data Center Bridging. Since
+	  FCoE frames are a kind of Ethernet frames, communication between
+	  FCoE clients and servers is limited to a single Ethernet broadcast
+	  domain.
