Abstract
Method and apparatus for controlling an operating mode of an Ethernet media access controller (MAC) embedded in a programmable device is described. In some examples, a configuration circuit is configured to receive a configuration signal from configuration memory of the programmable device and a host signal from a host bus of the programmable device, and configured to output a control length check disable signal the value of which depends on the value of at least one of the configuration signal or the host signal. A parameter check circuit is configured to receive a control signal derived from at least one of the control length check disable signal or the configuration signal, and configured to selectively disable checking a length of each control frame in frames received by the Ethernet MAC based on a value of the control signal.
