+Subject: [PATCH] Fix build with musl
+
+Upstream-Status: Pending
+
+Due to both <netinet/in.h> and <linux/in6.h> being included, the
+in6_addr is being redefined: once from the C library headers and once
+from the kernel headers. This causes some build failures with for
+example the musl C library:
+| In file included from ../../libnl-3.2.28/include/linux-private/linux/if_bridge.h:18:0,
+|                  from ../../libnl-3.2.28/lib/route/link/bridge.c:26:
+| /mnt/ale-build/tmp/musl/sysroots/itmk2/usr/include/linux/in6.h:32:8: error: redefinition of 'struct in6_addr'
+|  struct in6_addr {
+|         ^~~~~~~~
+| In file included from /mnt/ale-build/tmp/musl/sysroots/itmk2/usr/include/arpa/inet.h:9:0,
+|                  from ../../libnl-3.2.28/include/netlink-private/netlink.h:33,
+|                  from ../../libnl-3.2.28/lib/route/link/bridge.c:20:
+| /mnt/ale-build/tmp/musl/sysroots/itmk2/usr/include/netinet/in.h:23:8: note: originally defined here
+
+In order to fix this, use just the C library header <netinet/in.h>.
