Hello,
We are trying to build an application over DPDK, but we are getting this
warning when we call
rte_eal_init().
EAL: Detected 24 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: No available hugepages reported in hugepages-1048576kB

rte_eal_init() is returning successfully, but we wanted to know why this
warning is coming and
what are the potential issues that may arise due to this warning.
Note: NIC is bound with igb_uio. Hugepages are mapped and there are
enough free pages.
