-//! \file dhcp.c
-//! \brief DHCP APIs implement file.
-//! \details Processig DHCP protocol as DISCOVER, OFFER, REQUEST, ACK, NACK and DECLINE.
-//! \version 1.1.0
-//! \date 2013/11/18
-//! \par  Revision history
-//!       <2013/11/18> 1st Release
-//!       <2012/12/20> V1.1.0
-//!         1. Optimize code
-//!         2. Add reg_dhcp_cbfunc()
-//!         3. Add DHCP_stop() 
-//!         4. Integrate check_DHCP_state() & DHCP_run() to DHCP_run()
-//!         5. Don't care system endian
-//!         6. Add comments
-//!       <2012/12/26> V1.1.1
-//!         1. Modify variable declaration: dhcp_tick_1s is declared volatile for code optimization
