Also, do we lack the defines IFF_LOOPBACK, IFF_UP, IFF_BROADCAST, and IFF_MULTICAST? I can't find them anywhere, except in comments. For example, a grep for IFF_LOOPBACK shows it in the comments for getifaddrs(): [[[ * Depending on whether the bit IFF_BROADCAST or IFF_POINTOPOINT is * set in ifa_flags (only one can be set at a time), either * ifa_broadaddr will contain the broadcast address associated with * ifa_addr (if applicable for the address family) or ifa_dstaddr * will contain the destination address of the point-to-point * interface. ]]] but no such define exists in NuttX.
