Configuring Driver Parameters
Two new capabilities have been added to the parameters you can change using the ndd utility: nic_tracing and link_negotiation. The following procedure reflects these changes and replaces the section by the same name in the Sun GigabitEthernet PCI Adaper 1.0 User’s Guide.
▼To Temporarily Change a Parameter
Use the ndd(1M) utility to temporarily change a parameter. This change is lost when you reboot the system.
●To access the parameters you can change using ndd type the following command:
#ndd /dev/vge '?'
The system returns the following:

stat_ticks | (read and write) |
send_max_coalesced_bds | (read and write) |
recv_max_coalesced_bds | (read and write) |
nic_tracing | (read and write) |
link_negotiation | (read and write) |
