NetBSD 6.1.5 - man page for eshconfig (netbsd section 8)

ESHCONFIG(8)			   BSD System Manager's Manual			     ESHCONFIG(8)

NAME
     eshconfig -- configure Essential Communications' HIPPI network interface

SYNOPSIS
     eshconfig [-estx] [-b bytes] [-c bytes] [-d filename] [-i usecs] [-m bytes] [-r bytes]
	       [-u filename] [-w bytes] [interface]

DESCRIPTION
     eshconfig is used to configure device-specific parameters and download new firmware to the
     Essential Communications RoadRunner-based HIPPI network interface.  The interface is very
     sensitive to the DMA performance characteristics of the host, and so requires careful tuning
     to achieve reasonable performance.  In addition, firmware is likely to change frequently,
     which necessitates a reasonably easy way to update that firmware.

     Available operands for eshconfig:

     -b bytes
	     Adjust the burst size for read (by NIC of host memory) DMA.

     -c bytes
	     Adjust the burst size for write (by NIC of host memory) DMA.

     -d filename
	     Filename for file to download into NIC firmware.  This must be a file in the stan-
	     dard Essential format, with :04 preceding every line, and a tag line at the end
	     indicating the characteristics of the firmware file.

     -e      Write data to EEPROM.  Normally, setting tuning parameters will only persist until
	     the system is rebooted.  Setting this parameter ensures that the changes will be
	     written to EEPROM.

     -i usecs
	     Interrupt delay in microseconds.

     -m bytes
	     Minimum number of bytes to DMA in one direction (read or write) before allowing a
	     DMA in the other direction.  Tuning this prevents one direction from dominating the
	     flow of bytes, and artificially throttling the NIC.

     -r bytes
	     Bytes before DMA starts for read (from host to NIC).  This controls how soon the DMA
	     is triggered;  until this many bytes are requested, the DMA will not begin.

     -s      Show statistics for the HIPPI NIC.  Repeat the option to suppress non-zero statis-
	     tics.

     -t      Show current tuning parameters on the host.

     -u filename
	     Name of file to which the NIC firmware should be uploaded.  Not currently supported.

     -w bytes
	     Number of bytes required before write (from NIC to host) DMA is started.  Until this
	     many bytes are ready to be written, the DMA will not start.

     -x      Reset the NIC.  This is necessary for the HIPPI-FP support, as ifconfig(8) will no
	     longer physically reset the NIC when the interfaces goes up and down.

     Only the super-user may modify the configuration of a network interface.

DIAGNOSTICS
     Messages indicating the specified interface does not exist or the user is not privileged and
     tried to alter an interface's configuration.

SEE ALSO

HISTORY
     The eshconfig command first appeared in NetBSD 1.4.
