I agree that file is incorrect.  I simply quoted its use as it is the only
example in a commonly available layer.  I'll send a patch for the meta-ti
file and hopefully they'll fix it.

Here's what I use in my own layers [which are not public, sorry]
   $ cat meta-some-target/recipes-core/netbase/netbase_5.0.bbappend
   FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:"
   PACKAGE_ARCH = "${MACHINE_ARCH}"

This will pick up the interfaces file from ".../meta-some-target/recipes-core/netbase/netbase-5.0/${MACHINE}/interfaces"

As for the "__" scattered in the email - those crept in with Eddy's reply.
