DPDK is >triple licensed, whcih isn't in and of itself a big deal, but indications of which file(s) are under which license is fairly scattered.  For instance:

Something just like what you said above added to a LICENSE file in
the root directory of the project source would go a long way towards
clarifying the licensing issues for the distributions that may want
to package DPDK.
