This patch looks good.

Just want to point out that there are some places in the same doc that
needs fixing.  For example, in the various diagrams, specific versions of
DPDK and ESXi are used.  I understand that vmxnet3 pmd was introduced in
1.6 but I prefer them to be version-agonostic since the same diagram works
for 1.7, 1.8, etc and I don’t see much benefits in spelling out 1.6 in
this case.  Same arguments to the ESXi version.
