Including <sys/socket.h> before <net/if.h> shouldn't be needed #67
Description
While including <net/if.h> in my project I got following issues:
/project/path/_build/armv7m4-stm32l4x6-ismart2/include/net/if.h:63:19: error: field 'ifru_addr' has incomplete type
63 | struct sockaddr ifru_addr;
| ^~~~~~~~~
/project/path/_build/armv7m4-stm32l4x6-ismart2/include/net/if.h:64:19: error: field 'ifru_dstaddr' has incomplete type
64 | struct sockaddr ifru_dstaddr;
| ^~~~~~~~~~~~
/project/path/_build/armv7m4-stm32l4x6-ismart2/include/net/if.h:65:19: error: field 'ifru_broadaddr' has incomplete type
65 | struct sockaddr ifru_broadaddr;
| ^~~~~~~~~~~~~~
/project/path/_build/armv7m4-stm32l4x6-ismart2/include/net/if.h:66:19: error: field 'ifru_netmask' has incomplete type
66 | struct sockaddr ifru_netmask;
| ^~~~~~~~~~~~
/project/path/_build/armv7m4-stm32l4x6-ismart2/include/net/if.h:67:19: error: field 'ifru_hwaddr' has incomplete type
67 | struct sockaddr ifru_hwaddr;
Including <sys/socket.h> before <net/if.h> in application fix the problem, but it shouldn't be needed
Problem cannot be fixed by including <sys/socket.h> in <net/if.h> (as in Linux) because there are problem with building LWIP then.
