New file containing optimized receive and transmit functions which use 128bit vector instructions to improve performance. When conditions permit, these functions will be enabled at runtime by the device initialization routines already in the PMD. The compilation of the vectorized RX and TX code paths is controlled by a new setting in the build time configuration for the IXGBE driver. Also added is a setting which allows an optional further performance increase by disabling the use of the olflags field on packet RX.
