 This is a zero-copy driver uses the TivaWare ((C) TI) ROM function mapping macros, is intended for use with FreeRTOS+TCP BufferManagmeent_1, and is loosely modeled after the example lwIP Ethernet driver provided by TI in their TivaWare library. The driver utilizes the Ethernet (MAC) DMA engine.
 
-## Known Issues
-The configuration of vendor supplied tools and libraries used in this driver cause compiler warnings related to the Code Composer Studio ((C) TI) specific *pack_struct_start.h* and *pack_struct_end.h* port headers, though they appear to be benign. If there are suggestions for preventing these warnings, please let me know.

 ## Vendor Provided Version Numbers Used
 The following versions for tools/libraries were used during development and testing of this driver:
 - Code Composer Studio - 11.1.0.000111
