dpdk: disable unused rxtx callbacks in ethdev
Save a few cycles on every rx and tx burst call by not compiling in support for DPDK Rx and Tx callbacks. This feature is optional and unused by current VPP code. Change-Id: I1916bc8822e2bd405c1ac3909e85467a01023862 Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
