Self-Test Descriptions,
Continued
Sets up the SGEC data structures and initializes the SGEC
chip, which causes the SGEC to perform a single word DMA
read to the system memory.
SGEC Internal Loopback test
Verifies the correct operation of the SGEC transmitter and
receiver during an internal loopback. It also verifies the
burst-mode DMA read and write on non-word-aligned data
buffers for packets of different lengths and data patterns.
SGEC Interrupt test
Enables, forces, and services the SGEC interrupts for
initialization, transmission, and reception using internal
loopback.
SGEC CRC test
Tests the SGEC CRC generation on transmission. It checks
for detection of a bad CRC on reception using internal
loopback.
SGEC Receive MISS/BUFF test
Checks SGEC operation for missed packets and buffer error
during reception with internal loopback.
SGEC Collision test
Verifies collision detection and retry during transmission with
internal loopback.
SGEC Address Filtering test
Tests the SGEC receiver address filtering for broadcast,
promiscuous, and null destinations during internal loopback.
