bond: tx performance enhancement part deux
- Reduce per packet cost by buffering the output packet buffer indexes in the queue and
process the queue outside the packet processing loop.
- Move unnecessary variable initialization outside of the while loop.
- There is no need to save the old interface if tracing is not enabled.
Test result for 256 bytes packet comparison. Other packet size shows similar improvement.
