Appendix E. Token.lan and LAN Client Driver Parameters
In addition to the standard Novell keywords (such as slot, port, int, and frame), a
number of custom keywords are available in the driver. This list is dynamic: it
changes as support is added for new hardware as ODI specifications change. If it is
known, the driver revision level in which the keyword is available is included. This
list describes those keywords that are available and useful to users. All of these
keywords are optional unless otherwise noted.
Note: Some parameters, if misused, can cause problems with adapter operation

and must be set with a thorough understanding of adapter operations.
By default, the driver will first try to open on the ring in full-duplex mode
(connected to a switched Token-Ring network) on those adapters that are
capable of this function. Otherwise, it will try to open in half-duplex mode (a
traditional shared-media LAN). The presence of this keyword will prevent
the attempted open in full-duplex mode.
Shallow-mode operation is fast-path transmit, fast-path receive, and no LLC
processing (802.2) by adapter firmware. NoShallowmode is fast-path
transmit, standard receive, and 802.2 processing. Shallowmode is the
default on turbo-class adapters and is designed for higher performance.
Including this keyword will disable fast-path receive and enable LLC
processing on the adapter.
This PCMCIA-specific keyword is used to enable autoringspeed detection of
the adapter on the ring when the ring speed is not known or changes
because of mobility needs (for exampke, with a laptop). The first adapter
that opens on the ring must define the ring speed, and therefore cannot use
the autoringspeed keyword. Adapters opened subsequently can
automatically adjust to the ring speed by use of the autoringspeed keyword.
If the first adapter to try to open on the ring has the autoringspeed keyword
specified, the opening will fail.
Valid in shallowmode operation only. During normal (shallowmode) receive
processing, the host is interrupted after every buffer is received. Use of this
keyword reduces the number (and processing overhead) of interrupts per
frame, but lowers overall receive performance. Use this keyword on slower
machines or on fast machines that are heavily loaded.
Default: 1
Range 0-125
The numbef of adapter service access points that can be open at one time.
This parameter is not used in the ODI environment and should not be used
unless an application specifically requires it.
