Reset isolation for the GMAC_SW allows the switch function to remain active in during all device resets except for POR pin reset and ICEPICK COLD reset. Packet traffic to/from the GMAC_SW host will be flushed/dropped, but the ethernet switch will remain operational for all traffic between external devices on the switch even though the device is undergoing a device reset. Pin mux configuration for ethernet related I/O and reference clocks needed by the GMAC_SW to be active is controlled by a protected control module bit.
