.Sh DESCRIPTION
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
Available operands for
|
|
.Nm eshconfig :
|
|
.Bl -tag -width Ds
|
|
.It Fl b
|
|
Adjust the burst size for read (by NIC of host memory) DMA.
|
|
.It Fl c
|
|
Adjust the burst size for write (by NIC of host memory) DMA.
|
|
.It Fl d
|
|
Filename for file to download into NIC firmware.
|
|
This must be a file in the standard Essential format, with :04 preceding
|
|
every line, and a tag line at the end indicating the characteristics
|
|
of the firmware file.
|
|
.It Fl 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.
|
|
.It Fl m
|
|
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.
|
|
.It Fl r
|
|
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.
|
|
.It Fl s
|
|
Show statistics for the HIPPI NIC.
|
|
Repeat the option to suppress non-zero statistics.
|
|
.It Fl t
|
|
Show current tuning parameters on the host.
|
|
.It Fl u
|
|
Name of file to which the NIC firmware should be uploaded.
|
|
Not currently supported.
|
|
.It Fl w
|
|
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.
|
|
.It Fl x
|
|
Reset the NIC. This is necessary for the HIPPI-FP support, as
|
|
.Xr ifconfig 8
|
|
will no longer physically reset the NIC when the interfaces goes
|
|
up and down.
|
|
.El
|
|
.Pp
|
|
Only the super-user may modify the configuration of a network interface.
|
|
.Sh DIAGNOSTICS
|
|
Messages indicating the specified interface does not exist
|
|
or the user is not privileged and
|
|
tried to alter an interface's configuration.
