The XPS_LL_FIFO eop_n does not function correctly. The issue is restricted to the TX-side LocalLink. The problem manifests itself as two consecutive (i.e., back-to-back) EOP-beats issued on the TX LocalLink out of the core; this ends up breaking the downstream user logic.
This issue has been fixed in the xps_ll_fifo_v1_02_a, and is available in EDK 11.1.
