 tcm_qla2xxx jam_host attribute
 ------------------------------
 There is now a new module endpoint atribute called jam_host
-attribute: jam_host: boolean=0/1
+attribute::
+
+	jam_host: boolean=0/1
+
 This attribute and accompanying code is only included if the
 Kconfig parameter TCM_QLA2XXX_DEBUG is set to Y
+
 By default this jammer code and functionality is disabled
 
 Use this attribute to control the discarding of SCSI commands to a
 selected host.
+
 This may be useful for testing error handling and simulating slow drain
 and other fabric issues.
 
 Setting a boolean of 1 for the jam_host attribute for a particular host
- will discard the commands for that host.
+will discard the commands for that host.
+
 Reset back to 0 to stop the jamming.
