DPDK source archives are .tar.xz or .tar.gz, not .zip. Use .tar.xz in the instructions, since that is what the main download page links to. Also, correct the archive file and directory name capitalization. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Acked-by: John McNamara <john.mcnamara@intel.com>
