89665ec20c test/mempool_perf: support default mempool
Mempool_perf autotest currently does perf regression for:
 * nochache
 * cache

Introducing default_pool, mainly targeted for ext-mempool regression
test. Ext-mempool don't need 'cache' modes so only adding test-case
support for 'nocache' mode.

So to run ext-mempool perf regression, user has to set
RTE_MBUF_DEFAULT_MEMPOOL_OPS="<>"

There is chance of duplication  ie.. if user sets

RTE_MBUF_DEFAULT_MEMPOOL_OPS="ring_mp_mc" then regression
will happen twice for 'ring_mp_mc'

cbee51be40 test/mempool: support default mempool
Mempool test currently supports:
 * ring_mp_mc
 * stack

Adding a new default pool options. So, ring* + stack + default
(which can be 'stack' or 'ring')
 * This way, whatever the value of RTE_MBUF_DEFAULT_MEMPOOL_OPS is set,
   it would be verified.
 * even if that means duplicating some test (for example when "stack" is
   set as default and it already part of standard test)

c6b3570f9e mk: link app with ring mempool by default
From the discussion in [1], it was observed that application should
have a default pool already linked even in case of shared builds.
Ring is especially important because packet mbuf creation API refer to
ring_mp_mc as default handler.

Documentation for this is pending.

727d83ca23 net/virtio-user: fix multi-process attach
Secondary process doesn't properly attach to the rte_eth_device
initialized by the primary process.

Accessing device from secondary process (e.g. via rte_eth_rx_burst),
causes process to crash. because rte_eth_dev_data is not properly set.

The issue was flood by
'commit 7f95f78a8a ("ethdev: clear data when allocating device")'
which now clears rte_eth_dev_data entry.
For pci devices the struct is initialized by rte_eth_dev_pci_probe
->eth_dev_attach_secondary().
However, for virtio-user virtio_user_pmd_probe() is called instead of
rte_eth_dev_pci_probe().

The fix is to call rte_eth_dev_attach_secondary(), for secondary
process, from virtio_user_pmd_probe.
