The test generates and sends out the desired number of packets (a tunable parameter) and expects to receive the same number of packets through the loopback interface, external or internal. ![]() For the purpose of this test, a packet is defined as an Ethernet header followed by the Ethernet data payload (refer to the IEEE 802.3z standard). ![]() The netlbtest uses DLPI RAW mode to talk to the device driver. The netlbtest runs in loopback (external/internal) mode. These devices include eri (the Ethernet device in the RIO chip) and ge (Gigabit Ethernet), ce (GigaSwift Ethernet), dmfe (10/100 Mbps Ethernet), and vca (Sun Crypto Accelerator 4000). It provides functional test coverage of the devices which have device drivers that support the Ethernet loopback test. The netlbtest replaces the gemtest previously included in SunVTS.
