Appendix B Configuring the Sun Quad FastEthernet Device Driver Parameters 63
Defining the Number of Back-to-Back Packets
to Transmit
The
pace_size
parameter (see
TABLE B-6
) defines the maximum number of back-to-
back packets you can transmit at one time. If the value is zero, there will be no limit
to the number of back-to-back packets that can be transmitted.
Parameters That Report Transceiver Capabilities
TABLE B-7
describes the read-only transceiver capabilities. These parameters define
the capabilities of the local transceiver.
TABLE B-6
Back-to-Back Packet Transmission Capability
Parameter Values
pace_size
1 to 255 = Number of back-to-back packets transmitted at one time
0 = No limit to the number of back-to-back packets that can be transmitted
(default)
