[dpdk-dev] [PATCH 0/2] Allow application set mempool handle

Some platform can have two different NICs for example external PCI Intel
40G card and Integrated NIC like vNIC/octeontx/dpaa2.

Both NICs like to use their preferred pool e.g. external PCI card/ vNIC's
preferred pool would be the ring based pool and octeontx/dpaa2 preferred would
be ext-mempools.
Right now, Framework doesn't support such case. Only one pool can be
used across two different NIC's. For that, user has to statically set 
CONFIG_RTE_MEMPOOL_DEFAULT_OPS=<pool-name>.

So proposing two approaches:
Patch 1) Introducing eal option --pkt-mempool=<pool-name>
Patch 2) Introducing ethdev API called _get_preferred_pool(), where PMD driver
gets a chance to advertise their pool capability to the application. And based
on that hint- application creates pools for that driver.

  eal: Introducing option to set mempool handle
  ether/ethdev: Allow pmd to advertise preferred pool capability
