Details:

In most systems. 

struct sockaddr is defined as:

struct sockaddr {
unsigned   short   sa_family;
           char    sa_data[14];
};

Definition of the lwip current method of sockaddr may cause compatibility
problems. 

for example: (a wifi driver example)
======================================================
struct sockaddr    tmp;
memset(&tmp.sa_data, 0, 14);
======================================================
