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)

TABLE B-7 Read-Only Transceiver Capabilities

Parameter Description

autoneg_cap Local transceiver capability of the hardware

0 = Not capable of autonegotiation

1 = Autonegotiation capable

100fdx_cap Local transceiver capability of the hardware; initialized at startup

0 = Not 100 Mbit/sec full-duplex capable

1 = 100 Mbit/sec full-duplex capable

100hdx_cap Local transceiver capability of the hardware; initialized at startup

0 = Not 100 Mbit/sec half-duplex capable

1 = 100 Mbit/sec half-duplex capable

10fdx_cap Local transceiver capability of the hardware; initialized at startup

0 = Not 10 Mbit/sec full-duplex capable

1 = 10 Mbit/sec full-duplex capable

10hdx_cap Local transceiver capability of the hardware; initialized at startup

0 = Not 10 Mbit/sec half-duplex capable

1 = 10 Mbit/sec half-duplex capable

1 2 ... 76 77 78 79 80 81 82 83 84 85 86 ... 105 106
