> Can you use 1G hugepages instead of 2M pages or a combo of the two, not s=
ure how dpdk handles having both in the system?

Unfortunately, no. Some of our customer deployments are tenancies on KVM ho=
sts and low-end appliances, which are not configurable by the end user to e=
nable 1G huge pages.

I think we are going to have to revert this patch set from our build, as I =
don't see any other alternative for using DPDK 18 whilst remaining complian=
t to the POSIX/glibc requirements.
