Zynq-7000 AP SoC, GigE - Packets up to 1536 bytes are Allowed with VLAN Tagging

描述

The IEEE 802.3 specification states that the maximum size of a non-jumbo packet should be 1518 bytes. With VLAN tagging, this maximum size is raised to 1522 bytes. When the Receive 1536-Byte Frames bit is set, gem.NET_CFG[8] = 1, the controller allows up to 1536 bytes in the packet to be received when the controller should only allow up to 1522 bytes.

解决方案

Impact:
Trivial. Some packets will be accepted that are larger than 1522 bytes.
Work-around:
None.
Configurations Affected:
Systems that use the GigE controller and want to define the packet size using the Receive 1536-Byte Frames bit..
Device Revision(s) Affected:
All. No plan to fix. Refer to (Xilinx Answer 47916) Zynq-7000 AP SoC Silicon Revision Differences Answer Record.
