- SIOCGIFCONFIG: reads and enumerate all the network interfaces - SIOCGIFADDR: reads network address for a given interface - SIOCGIFFLAGS: reads network flags for a given interface - SIOCGIFNETMASK: reads network netmask for a given interface - SIOCGIFBRDADDR: reads network broadcast address for a given interface - SIOCGIFDSTADDR: reads peer destination address for a given interface (not supported for Windows) This change defines Linux ABI structs for the above interfaces and adds polyfills to ensure they behave consistently on XNU and Windows.
