When the emulation suspend state is entered, the EMAC will stop processing receive and transmit frames
at the next frame boundary. Any frame currently in reception or transmission will be completed normally
without suspension. For transmission, any complete or partial frame in the transmit cell FIFO will be
transmitted. For receive, frames that are detected by the EMAC after the suspend state is entered are
ignored. No statistics will be kept for ignored frames.
