Add support for vdev tap devices
This commit adds support for the creation of tap devices. To create a tap device, and associate it with a DPDK port, add within the port section: vdev=<tap_name> local ipv4=<ip_assigned_to_port> <tap_name> will appear as a kernel network device, with an IP <ip_assigned_to_port> ARP packets received from the network on the DPDK interface will be forwarded to the kernel. 1st packet which needs to be generated to a new IP will cause an IP packet to be sent to the kernel (using socket sendto) forcing the kernel to send an ARP_REQUEST. In this commit, there is no notification from the kernel about ARP table changes. This is subject to further commits. Two config files, gen_tap.cfg and swap_tap.cfg have been created. They work one against each other. *** Note however that they do not work if running within the same host (with the port being connected back to back) *** This is due to the fact that the kernel would bypass the ports and use local interface...
