  In i40e PMD, for fast_free path in Tx, freeing mbufs firstly need to do
an extra memcpy due to the special structure of ‘txep’.
Thus, replaced the put_bulk function with the zero-copy put API to
avoid the cost of this memcpy
On Ampere-altra server, for single-core DPDK l3fwd test, throughput
improves by 5% with the new API

v4:
Added the Depends-on tag
v3:
Fixed the way mbufs are accessed from txep (Morten Brorup)
v2:
Fixed the code for n > RTE_MEMPOOL_CACHE_MAX_SIZE (Morten Brorup)
v1:
1. Integrated the zc_put API in i40e PMD
2. Added mempool test cases with the zero-cpoy API's

Kamalakshitha Aligeri (2):
  net/i40e: replace put function
  test/mempool: add zero-copy API's
