9.2i EDK SP2 - xps_ll_temac_v1_00_b, TX Checksum offloading is broken, and the XPS LL Temac example code has Checksum Offload test code commented out

Description

In version v1_00_b of the xps_ll_temac, TX CSUM off loading is broken, and the Checksum Offload example code for the XPS LL Temac core, "xlltemac_example_intr_sgdma.c," is commented out so this test does not run.

When the test code for Checksum Offload is uncommented and run, the following error occurs:

"Temac: Rx packet rejected"

Solution

The corrected x_ll_if.vhdl file that fixes this issue is available at:

The issue will be fixed in xps_ll_temac_v1_01_a of the xps_ll_temac in EDK 10.1 and will be available at:
