The netbase_4.45.bbappend recipe in $POKY_ROOT/meta-yocto/recipes-core/netbase looks wrong. $POKY_ROOT/meta-yocto/recipes-core/netbase contains a folder named netbase-4.45/. The netbase_4.45.bbappend recipe contains: FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:" The expression "${THISDIR}/${PN}:" will expand to "$POKY_ROOT/meta-yocto/recipes-core/netbase/netbase:" but should expand to "$POKY_ROOT/meta-yocto/recipes-core/netbase/netbase-4.45:". To generate the correct path ${PV} must be added, netbase_4.45.bbappend should look like: FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:"
Your right this is a straight forward enough fix, care to send a patch, I can help you with the patch creation if needed.
