NOTE:
If you are using the SBA or ESS feature,
the driver will start SBA immediately at driver
initialization. The driver will immediately request
synchronous bandwidth after initialization. Both
the SBA and ESS may be active on the
same network adapter. But only one SBA may be
active in the same network.
Configuration parameter indicated with a "*" are not currently
provided by the driver's configuration environment.
* USER Data
User data to be passed to the SMT.
* PMF password
Parameter Management Frame (PMF) password for the adapter. A nonzero PMF
password enables authorization checking of the adapter for remote change
requests. A PMF password of 0 disables the authorization checking of the
adapter. The PMF password consists of 16 hexadecimal digits. Default value
is 0.
SMT T-Req
This parameter provides local write access to the T-Req value that is
registered as fddiMAC 51 in the SMT Standard. The value for T-Req is
specified in milliseconds. The valid range is between 5 ms and 165 ms.
If any value is specified which is outside the limits, the upper/lower
limit will be used. If no value is specified, the default value for T-Req
(165 ms) will be used.
SMT TVX lower bound
This parameter provides local write access to the TVX attribute
registered as fddiMAC 54 in the SMT Standard. This attribute provides
local control of the recovery time from transient ring errors. The
value for TVX is specified in microseconds. The valid range is between
2500 us and 10000 us. If a value is specified outside the limits, the
upper/lower limit is used. If no value is specified the default value for
TVX (2700 us) is used.
NOTE:
Due to hardware limitations the upper value for the TVX attribute is
restricted to 5200 us. It is recommended to specify a value below this
limit.
Alternate MAC/SMT Address
This address describes the MAC address that is used as the adapter's
alternate network address. A valid address consists of 12 hexadecimal
digits. The default value is none, in which case the adapter's factory
address is used.
SBA_Payload
This parameter defines the requested synchronous bandwidth for manual
static allocations. The valid range is between 0 and 1562 bytes per
125 us. For example: if the required bandwidth is 1 MBits/s
(125,000 Bytes/s), the value of the payload is 125,000 * 125E-6 = 15.625
round up to 16. If a value outside the limits is specified, the upper/
lower limit will be used. The default value is zero which means no
synchronous bandwidth is used. The user is required to define the amount of
bandwidth to be able to send synchronous frames. If this parameter is not
specified, the keyword "SBA_OverHead", "MaxTneg", "MinSegmentSize", and
"SBA_Category" have no effect. The end station supports either the static
allocation model, if the requested payload is specified by the parameter
"SBA_Payload", or the dynamic allocation model, where the required
synchronous bandwidth is allocated by a multimedia application. If a
multimedia application is used that can dynamically allocate the bandwidth,
the parameter SBA_PayLoad should not be specified.
SBA_Overhead
This parameter defines the requested overhead for static allocations.
The valid range reaches from 0 to 5000 bytes. If a value is specified
which is outside the limits, the upper/lower limit is taken. The default
value is 50 bytes. This parameter has no effect, unless the parameter
SBA_PayLoad is specified.
MaxTneg
This parameter defines the maximum token rotation delay that is acceptable
to the application(s) using synchronous bandwidth. The valid range is
between 5 ms and 165 ms. If a value is specified outside the limits, the
upper/lower limit is used. The default value is 25 ms. This parameter has
no effect, unless the parameter SBA_PayLoad is specified.
MinSegmentSize
This parameter defines the minimum synchronous segmentation size. The
value corresponds to the amount of bytes to be transmitted on a per token
opportunity. The valid range is between 1 and 4478 bytes. If a value is
specified which is outside the limits, the upper/lower limit is used. The
parameter has no effect unless the parameter SBA_PayLoad is specified.
* SBA_Category
This parameter defines the session ID of the SBA_Category for the static
allocation.The valid range is between 0 and 65535. If a value is specified
which is outside the limits, the upper/lower limit will be taken. This
parameter has no effect, unless the parameter SBA_PayLoad is specified.
Sync_Tx_Mode
This keyword defines the synchronous transmission mode. The default value
is "SPLIT" which means that only packets identified as synchronous packets
will be transmitted via the synchronous queue. The other value is "ALL"
which means that all LLC packets received from upper layers are transmitted
via the synchronous queue. This keyword has no effect, unless the end
station support was able to get the required synchronous bandwidth from the
SBA.
SBA_Command
This parameter specifies an SBA local action to start/stop the SBA of the
network device. Valid values are "START" and "STOP". The default value is
"STOP".
SBA_Available
This parameter specifies the maximum synchronous bandwidth in percent
available for the primary path. If the value is outside the valid range,
the upper/lower limit is used. The valid range is 0-100. The default value
is 50.
For most PCI adapters, no special setup procedure is
required. Consult your hardware documentation for more
information.
