Detailed Description
Common functions used throughout the stack.
These are reference implementations of the byte swapping functions. Again with the aim of being simple, correct and fully portable. Byte swapping is the second thing you would want to optimize. You will need to port it to your architecture and in your cc.h:
#define lwip_htons(x) your_htons #define lwip_htonl(x) your_htonl
Note lwip_ntohs() and lwip_ntohl() are merely references to the htonx counterparts.
If you #define them to htons() and htonl(), you should #define LWIP_DONT_PROVIDE_BYTEORDER_FUNCTIONS to prevent lwIP from defining htonx/ntohx compatibility macros.
