config FCST tristate "SCST FCoE target module" depends on LIBFC && SCST help 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.
