Ten Gigabit Ethernet MAC - v14.0 Rev.1 - Example Design TX FIFO only operates at full throughput if In-band FCS and custom preamble are disabled

描述

When using the Ten Gigabit Ethernet MAC v14.0 Rev.1 and earlier (available in Vivado 2014.4 and earlier),  the example Design TX FIFO only operates at full throughput if In-band FCS and custom preamble are disabled. 

If In-band FCS and custom preamble are enabled, then IFG between frames can be larger than the min IFG of 12 bytes even if frames are input to the example design FIFO back to back.

解决方案

The 10G AXI Example design FIFO is being updated in 2015.1 to support full throughput with in-band FCS and custom preamble enabled.
