Communication between a host and the second chip is done by adding offload and completion tags to the ethernet frame header of frames associated with the offloaded networking task.

Abstract: A portable electronic device with cellular phone capability has a built-in hands-free headset. A carrying device for a portable electronic device with cellular phone capability has a built-in or attached hands-free headset. The headset is retractable, and is stored in the portable electronic device or the carrying device with a point-of-access externally accessible during periods of non-use, and can be pulled out for telephone conversation. The headset has a cord-winder providing internal storage for the cord. The cellular phone or the carrying device provides readiness of a hands-free headset and convenience of carrying the headset, thus it facilitates the use of hands-free headsets when appropriate.
