Subject: pad: Don't forward the allocation query by default
X-Git-Tag: RELEASE-0.11.2~177

pad: Don't forward the allocation query by default

This has to be handled explicitely by elements to
make sure that they support all the metas passed
in the allocation query.
Metas have to supported explicitely, otherwise the
query will fail. All elements in a chain need to
support a specific meta to allow its usage.
