Use v2' incorporating internal review comments as a base. Internal review done by Wenzhou Lu (Intel) and internal review versions and testing shown below v2': Incorporate Wenzhou's comments, remove superfluous assignment to fc.requested_mode in em_hardware_init function. Compiled and tested (via testpmd) on Ubuntu 14.04 on target x86_64-native-linuxapp-gcc Compiled for target x86_64-native-linuxapp-clang v1': Modified driver and eal code to support I217 and I218 Intel NICs. Compiled and tested (via testpmd) on Ubuntu 14.04 for target x86_64-native-linuxapp-gcc Compiled for target x86_64-native-linuxapp-clang M. Jay(Intel) had used the patch for DPDK demo.
