+Subject: [PATCH] dpdk v1.8.0: add RTE_KERNELDIR_OUT to split kernel build
+ artifact
+
+Introduce RTE_KERNELDIR_OUT to be the path to which kernel build
+artifacts are located. This is for matching the workflow change
+since Yocto Project v1.8 onwards whereby tmp/work-shared contains
+separate directories for kernel source and kernel artifacts.
+
+Upstream-Status: Inappropriate [configuration]
