[dpdk-dev] [PATCH v3 00/40] Fix build on gcc8 and various bugs

[Andy Green]

The following series gets current master able to build
itself, and allow lagopus to build against it, on Fedora 28 +
x86_64 using gcc 8.0.1.

The first 17 patches have already been through two spins and
this time are corrected for all the comment (thanks to
everybody who commented) since v2, and have tested-by /
acked-bys applied.  The first workaround patch for the hash
function cast problem is dropped since something has already
been applied in master since yesterday to address it.

The additional 23 patches are fixes for problems found
actually trying to build lagopus using current master.
These are almost entirely related to signed / unsigned
or truncation without explicit casts inside dpdk
headers.
