DPDK 18.11+ does its best to ensure all devices are
equally attached or detached in all processes within
a shared memory group. For SPDK it means that if
a device is hotplugged in the primary, then DPDK will
automatically send an IPC hotplug request to all other
processes. Those other processes may not have the same
SPDK PCI driver registered and may fail to attach the
device. DPDK will send back the failure status and the
primary process will also fail to hotplug its device.
To prevent that, we need to pre-register the pci
drivers on env init.
We register the drivers just after the EAL init
because we don't want the matching devices to be picked
up by the initial bus probe in DPDK. That's for 2 reasons:
1) we don't want to attach *all* available devices
2) devices attached from non-SPDK context (that is,
outside of the spdk attach or enumerate functions)
will still fail to attach - the entire attaching
process will only take significant amount of time
and will bloat the log with useless status messages
