The ocs_fc(4) driver supports the following hardware: Emulex 16/8G FC GEN 5 HBAS LPe15004 FC Host Bus Adapters LPe160XX FC Host Bus Adapters Emulex 32/16G FC GEN 6 HBAS LPe3100X FC Host Bus Adapters LPe3200X FC Host Bus Adapters The driver supports target and initiator mode, and also supports FC-Tape. Note that the driver only currently works on little endian platforms. It is only included in the module build for amd64 and i386, and in GENERIC on amd64 only.
