36 .Nd configure Essential Communications' HIPPI network interface
51 is used to configure device-specific parameters and download new firmware
52 to the Essential Communications RoadRunner-based HIPPI network interface.
53 The interface is very sensitive to the DMA performance characteristics
54 of the host, and so requires careful tuning to achieve reasonable
56 In addition, firmware is likely to change frequently, which necessitates
57 a reasonably easy way to update that firmware.
59 Available operands for
63 Adjust the burst size for read (by NIC of host memory) DMA.
65 Adjust the burst size for write (by NIC of host memory) DMA.
67 Filename for file to download into NIC firmware.
68 This must be a file in the standard Essential format, with :04 preceding
69 every line, and a tag line at the end indicating the characteristics
73 Normally, setting tuning parameters will only persist until the
75 Setting this parameter ensures that the changes will be written to
78 Interrupt delay in microseconds.
80 Minimum number of bytes to DMA in one direction (read or write)
81 before allowing a DMA in the other direction.
82 Tuning this prevents one direction from dominating the flow of
83 bytes, and artificially throttling the NIC.
85 Bytes before DMA starts for read (from host to NIC).
86 This controls how soon the DMA is triggered; until this many bytes
87 are requested, the DMA will not begin.
89 Show statistics for the HIPPI NIC.
90 Repeat the option to suppress non-zero statistics.
92 Show current tuning parameters on the host.
94 Name of file to which the NIC firmware should be uploaded.
95 Not currently supported.
97 Number of bytes required before write (from NIC to host) DMA
99 Until this many bytes are ready to be written, the DMA will not start.
102 This is necessary for the HIPPI-FP support, as
104 will no longer physically reset the NIC when the interfaces goes
