DESCRIPTION
     The esp driver provides support for the NCR 53C90, 53C94 and 53C96;
     Emulex ESP100, ESP100A, ESP200 and ESP406; and Qlogic FAS216 and FAS408
     SCSI controller chips found in a wide variety of systems and peripheral
     boards.  This includes the Qlogic ISA and VLB SCSI host adapters, and the
     Sun Fast SCSI buffered Ethernet for Sbus (FSBE/S, X1053A, Sun part #
     501-2015).

     For Qlogic PCI SCSI host adapters, use the isp(4) device.

CONFIGURATION
     The esp driver supports the following flags for use in config(1) files:

     bits 0-7:    disable disconnect/reselect for the corresponding SCSI tar-
                  get
     bits 8-15:   disable synchronous negotiation for the corresponding SCSI
                  target
     bits 16-23:  disable tagged queuing for the corresponding SCSI target

     "Target" is synonymous with SCSI ID number.

     Note that SCSI tape drives should be allowed to perform disconnect/rese-
     lect or performance will suffer.
