Broadcom Tüm modeller D1 kodu

Anlamı

Enables MAC loopback mode in the adapter and transmits 5000 Layer 2 packets of various sizes. As the packets are received back by Broadcom NetXtreme II User Diagnostics, they are checked for errors. Packets are returned through the MAC receive path and never reach the PHY. The adapter should not be connected to a network

• C4Verifies the packet cracking logic block (i.e., the ability to parse TCP, IP, and UDP headers within an Ethernet frame) as well as the checksum/CRC offload logic. In this test, packets are submitted to the chip as if they were received over Ethernet and the TPAT block cracks the frame (identifying the TCP, IP, and UDP header data structures) and calculates the checksum/CRC. The TPAT block results are compared with the values expected by Broadcom NetXtreme II User Diagnostics and any errors are displayed
• D2Enables PHY loopback mode in the adapter and transmits 5000 Layer 2 packets of various sizes. As the packets are received by Broadcom NetXtreme II User Diagnostics, they are checked for errors. Packets are returned through the PHY receive path and never reach the wire. The adapter should not be connected to a network
• D4Verifies the functionality of the adapter's Large Send Offload (LSO) support by enabling MAC loopback mode and transmitting large TCP packets. As the packets are received by Broadcom NetXtreme II User Diagnostics, they are checked for proper segmentation (according to the selected MSS size) and any other errors. The adapter should not be connected to a network
• D6Verifies the Receive Path Catch-up (RPC) block by sending packets to different transmit chains. The packets traverse the RPC logic (though not the entire MAC block) and return to the receive buffers as received packets. This is another loopback path that is used by Layer 4 and Layer 5 traffic within the MAC block. As packets are received by Broadcom NetXtreme II User Diagnostics, they are checked for errors. The adapter should not be connected to a network
