+Subject: [PATCH] libqmi: fix build when ARPHRD_RAWIP isn't defined in libc
+
+The kernel may be new enough to have rmnet support, but it could be
+that libc doesn't have ARPHRD_RAWIP defined yet; if so, just define it
+ourselves.
+
+Fixes http://autobuild.buildroot.org/results/c8853b7161bd85d46c1282c6c097e7ef4042ae68
