Note:
For release notes and known issues for v12.0 and later of the core, see (Xilinx Answer 54252).

The following table provides known issues for the 10-Gigabit Ethernet MAC core, starting with v11.1, initially released in ISE Design Suite 13.1.This is the first version to support 7 series devices and have an AXI interface. For earlier versions of the core using the legacy user interface, please refer to IP Release Notes Guide for the release notes answer record by version.

Note: The "Version Found" column lists the version the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
