This introduces bulk XDP_TX in veth.
Improves XDP_TX performance by approximately 9%. The detailed
explanation and performance numbers are shown in patch 2.

v2:
- Use stack for bulk queue instead of a global variable.

v3:
- Add act field to xdp_bulk_tx tracepoint to be in line with other XDP
  tracepoints.
