[dpdk-dev] [PATCH] ip_pipeline: Fix for performance issue in downstream configuration

In TM, the read size should be lesser than the write size to improve performance.
This enables the TM ports to push maximum packets to the output port.

This fix changes the burst_read value from 64 to 24 in default_tm_params.
