Re-submission of Bruce Richardson patch set:
http://dpdk.org/dev/patchwork/patch/12484/
This patchset is a rebase to the current head and use of
strndupa (not posix) was replaced.
Original cover letter:
This patchset is based on the work done by Jan Viktorin to add resource
handling to the test app. [1]
It takes the existing lpm large routing table information and converts it
from a header file included at compile time to a resource linked in. This
improves things in two ways:
1. Improves DPDK build time
2. Removes approx 1 million lines of code from our LOC counts, as the header
file no longer counts as code, but more correctly as data.
Before and after approx code stats (with some additional patchsets applied).
Notice how the app folder has dropped from being the biggest component with
6x the drivers code to second place with less code than the drivers.
Future work is to repeat the same process for lpm6.
