Embodiments of methods and apparatus for fast link recover are disclosed. One method includes sensing a link quality failure of a link between a receiver and a transmitter. If a link quality failure is sensed, then the receiver selects new pre-coder settings for the transmitter. The receiver communicates the new pre-coder settings to the transmitter. The transmitter applies the new pre-coder settings. The receiver computes its equalizer settings based on the new pre-coder settings of the transmitter. One apparatus or transceiver includes a means for determining a link quality failure of a link between the transceiver and a link partner transceiver. The transceiver selects new pre-coder settings for the link partner transceiver if a link quality failure is sensed. Additionally, the transceiver communicates the new pre-coder settings to the link partner transceiver, and computes its equalizer settings based on the new pre-coder settings of the link partner transceiver.

Method and apparatus for fast link recovery

An apparatus and method of interfacing physical layer (PHY) control with media access control (MAC) is disclosed. One method includes signaling to the PHY control to operate in a low-power mode when the MAC is detected to be transmitting idle patterns. The MAC transitioning from transmitting the idle patterns to transmitting data can be detected. When the transition is detected, the PHY control is signaled to transition to a wake up mode. Data from the MAC is buffered while the PHY control is in the wake up mode. The buffered data is provided to the PHY control after the PHY control has completed the wake up mode.
