vhost PMD has not been available for secondary processes since
DPDK v18.11.  (https://bugs.dpdk.org/show_bug.cgi?id=194)
(for a long term !)
This series of patches intend to make vhost PMD available for
secondary processes.
Because now setting vhost driver to communicate with a vhost-user
master (ex. Qemu) is accomplished by the probe function of the
primary process, only the primary process can be a vhost-user
slave.
With this patch, setting vhost driver is delayed at eth_dev
configuration in order to be able to set it from a secondary
process. Because (in the first place,) setting vhost driver is not
necessary to be done at probe (it is enough to be done up to eth_dev
start), this fix is no problem for the primary process.
There is a precondition that the same process has to operate
a vhost interface from begining to end (eth_dev configuration to
eth_dev close). (This patch leaves it to user's responsibility.)
This precondition will not be a problem in most use cases
(including SPP).

Itsuro Oda (4):
  net/vhost: remove an unused member
  net/vhost: allocate iface_name from heap
  net/vhost: delay vhost driver setup
  net/vhost: make secondary probe complete
