Oh, ok.

"make install" usually installs everything, including headers, 
documentation etc on top of binaries and libraries.  Thats more or less 
what the patches here do. For packaging purposes they're usually split 
up to different sub-packages and in the make-system there usually are 
separate targets for the individual elements like install-doc.

The notion of SDK in DPDK is something entirely different from how the 
average OSS project is used in development of other software. Some 
projects like pktgen-dpdk rely on the SDK structure, mk snippets and 
scripts and all, others like openvswitch try to deal with it more like 
it was any old OSS citizen.

In my packaging of DPDK I ended up providing both: headers, libraries 
etc in the normal system paths, and then a separate dpdk-sdk directory 
holding the SDK-parts like mk bits and symlinking to the libs and 
headers as needed, so that you can actually point RTE_SDK to that 
dpdk-sdk dir and be able to build apps against the thing.

I'd be surprised if somebody somewhere isn't relying on the current 
specific behavior, given its explicitly documented and all. Whether it 
needs to stay, and whether it needs to stay as the default ... I 
wouldn't miss it, but its a question for those using and depending on it 
really.
