Setting Parameters Using the ndd Utility

In addition to the e1000g.conf file, you can also use the ndd(1M) command to configure the e1000g driver.

#ndd -get /dev/e1000g0 ?

Using ndd(1M), you can set the link speed/duplex using the advertised capability parameters supported by the e1000g device. Each parameter contains a boolean value that determines if the device advertises that mode of operation. The adv_autoneg_cap parameter controls autonegotiation. When adv_autoneg_cap is set to 1, autonegotiation is performed and the link speed/duplex is autonegotiated to the mode determined by the first nonzero parameter in priority order as listed below:

adv_1000fdx_cap adv_100fdx_cap adv_100hdx_cap adv_10fdx_cap adv_10hdx_cap

1000Mbps full duplex 100Mpbs full duplex 100Mpbs half duplex 10Mpbs full duplex 10Mpbs half duplex

When adv_autoneg_cap is set to 0, the link speed/duplex is forced to the mode specified by force_speed_duplex. The valid values of force_speed_duplex and the corresponding modes are:

TABLE 4-1

Value

1

10 Mpbs half-duplex

2

10Mpbs full-duplex

3
