AR# 52025 Zynq-7000 AP SoC, GigE - Unicast and Broadcast Pause Frames Received by the Controller are not Filtered Out

Unicast and broadcast pause frames should be filtered out by the controller when the controller's Disable Copy of Pause Frames bit is set, gem.NET_CFG [23] = 1. However, this feature does not work and these pause frames will be passed on to memory regardless of this bit setting.

Pause frames rarely occur and when they do, the software can filter them out.

Impact:
Minor, requires software work-around.
Work-around:
Software can filter pause frames out of the data stream.
Configurations Affected:
Systems using GigE and want the hardware to filter out pause frames.
Device Revision(s) Affected: All. No plan to fix. Refer to (Xilinx Answer 47916) - Zynq-7000AP SoC Silicon Revision DifferencesAnswer Record
