[dpdk-dev] [PATCH 0/2] app/testpmd: improve multiprocess support

[Marcin Kerlin <marcinx.kerlin@intel.com>]

This patch ensure not overwrite device data in the multiprocess application.

1)Changes in the library introduces continuity in array rte_eth_dev_data[]
shared between all processes. Secondary process adds new entries in free
space instead of overwriting existing entries.

2)Changes in application testpmd allow secondary process to attach the mempool
created by primary process rather than create new and in the case of quit or
force quit to free devices data from shared array rte_eth_dev_data[].

Breaking ABI:
Changes in the library librte_ether causes extending existing structure 
rte_eth_dev_data with a new field lock. The reason is that this structure is
sharing between all the processes so it should be protected against attempting
to write from two different processes.

Tomasz Kulasek sent announce ABI change in librte_ether on 21 July 2016. I would
like to join to this breaking ABI, if it is possible.
