bond: tx optimizations
Break up bond tx function into multiple small workloads:
1. parse the packet header and hash it based on the configured algorithm
2. optionally, trace the packet
3. convert the hash value from (1) to the slave port
4. update the buffers with the slave sw_if_index
5. Add the buffers to the queues
6. Create and send the frames
