64 .It Va kern.cam.ctl.iscsi.debug
65 Verbosity level for log messages from the kernel part of iSCSI target.
66 Set to 0 to disable logging or 1 to warn about potential problems.
67 Larger values enable debugging output.
69 .It Va kern.cam.ctl.iscsi.maxtags
70 The number of outstanding commands to advertise to each iSCSI initiator.
71 Current implementation is not very accurate, so do not set this below 2.
