Enable PCI extended tags in the DPDK config
This change should improve DPDK performance on 40G+ NICs with small packets. It also removes ITR setting for i40e devices, allowing driver to set default. Change-Id: I70761b155e48fb0281f7c231516d83027bd16ca2 Signed-off-by: Damjan Marion <damarion@cisco.com>
