 The  DPDK igb_uio kernel module depends on traditional Linux kernel ``uio`` support to operate. Linux traditional ``uio`` support may be compiled as a module, so this module should be loaded using the ``modprobe`` program.
 Kernel must support the allocation of hugepages. Hugepage support is required for the large memory pool allocation used for packet buffers. By using hugepage allocations, performance will be improved  since only fewer pages are needed, and therefore less Translation Lookaside Buffers (TLBs, high speed translation caches), which reduce the time it takes to translate a virtual page address to a physical page address. Without hugepages, high TLB miss rates would occur, slowing performance.
