+Subject: [PATCH] netifaces: initialize msghdr in a portable way
+
+musl has padding bytes inside the msghdr struct which means initializing
+full structure will cause wrong assignments, doing partial assignment is
+more portable and assign the elements after that
+
+Fixes
+netifaces.c:1808:9: error: incompatible pointer to integer conversion initializing 'int' with an expression of type 'void *' [-Wint-conversion]
+        NULL,
+        ^~~~
