sys_attrs_lfa - lfa subsystem attributes
This reference page lists and describes attributes for the
lfa (lfa) kernel subsystem. This subsystem is used by the
HE622 and HE155 Asynchronous Transfer Mode (ATM) adapters.
Refer to the sys_attrs(5) reference page for an introduction
to the topic of kernel subsystem attributes.
The version number of the lfa driver. This is a
read-only attribute, and cannot be changed.
A value that enables (1) or disables (0) the awakening
of a separate thread to handle real interrupt
service work by the interrupt service routine.
Do not modify the default setting for this
attribute unless instructed to do so by HewlettPackard
Company support personnel or by patch kit
documentation.
Default value: 1 (enabled)
The number of Media Access Control (MAC) addresses
to generate for the lfa adapter. The adapter has
only one MAC address, but the driver can generate
unique locally administered addresses up to the
number specified.
Default value: 16 (addresses)
Minimum value: 1
Maximum value: 64
The number of bits to use for the Virtual Path
Identifier (VPI) field. A total of 12 bits can be
divided between the VPI and VCI (Virtual Channel
Identifier) fields.
The mapping of the valid num_vpi_bits values to the
different VPI and VCI ranges are as follows:
------------------------------
Value VPI Range VCI Range
------------------------------
0 0 0-4095
1 0-1 0-2047
2 0-3 0-1023
3 0-7 0-511
4 0-15 0-255
5 0-31 0-127
6 0-63 0-63
7 0-127 0-31
8 0-255 0-15
------------------------------
Default value: 0 (bits), or 12 bits for the VCI
Minimum value: 0
Maximum Value: 8
A value that enables (1) or disables (0) the use of
64-bit data transfers by the adapter. When
installed in a 64-bit PCI slot, the HE622 and HE155
adapters can perform 64-bit data transfers. To
force the driver to use 32-bit data transfers, set
this attribute to 0.
Do not modify the default setting for this
attribute unless instructed to do so by HewlettPackard
Company support personnel or by patch kit
documentation.
Default value: 0 (disabled)
