V1.1 - Added mac_tx_tfirst output to assist coupling to MAC layers that require a start of frame indication. |
Migration Notes: V1.0 to V1.1 |
- The entity declaration for UDP_Complete_nomac and IP_Complete_nomac have changed. |
- if you dont need to use the new mac_tx_tfirst output, leave it open. |

V1.0 - initial release |
