Subject: examples/ip_pipeline: use unsigned constants for left shift operations
X-Git-Tag: spdx-start~7450
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e04f6a64f158a2163fc47000b19d33d20a23e299;p=dpdk.git

examples/ip_pipeline: use unsigned constants for left shift operations

Tell the compiler to use unsigned constants for left shift ops,
otherwise building with gcc >= 6.0 fails due to multiple warnings like:
warning: left shift of negative value [-Wshift-negative-value]
