2.5.16. Intermittent Equalization Timeout or Speed Degrade during Link Disable, Hot Reset, Equalization Redo, and Speed Change

Description

In the GTS AXI Streaming Intel® FPGA IP for PCI Express*, when you perform link disable, hot reset, or speed change, there is a negligible chance of running into the equalization timeout or speed degradation. If equalization timeout occurs, the link is expected to re-attempt the transmitter equalization or retrain the link to achieve link up at the desired speed by default. If the link settles at the degraded link speed, an additional speed change request is required for the link to recover at the desired speed.
