+Subject: [PATCH] ip: rearrange and prune header files
+
+The recent report of issues with missing limits.h impacting musl
+suggested looking at what files are and are not included in ip code.
+
+The standard practice is to put standard headers first, then system,
+then local headers. Used iwyu to get suggestions about missing
+and extraneous headers.

+Subject: [PATCH] flower: replace XATTR_SIZE_MAX
+
+The flower tc parser was using XATTR_SIZE_MAX from linux/limits.h,
+but this constant is intended to before extended filesystem attributes
+not for TC. Replace it with a local define.
+
+This fixes issue on systems with musl and XATTR_SIZE_MAX is not
+defined in limits.h there.
