+- ``CONFIG_RTE_LIBRTE_DPAA_PMD`` (default ``n``)
+
+ By default it is enabled only for defconfig_arm64-dpaa-* config.

+- ``CONFIG_RTE_LIBRTE_DPAA_DEBUG_DRIVER`` (default ``n``)
+
+ Toggle display of generic debugging messages
+
+- ``CONFIG_RTE_LIBRTE_DPAA_DEBUG_INIT`` (default ``n``)

+- ``CONFIG_RTE_MBUF_DEFAULT_MEMPOOL_OPS`` (default ``dpaa``)
There are a few new config missing in documentation.
Those are some non-documented/hidden toggles which I don't want to
expose. Like *CHECKING. They are there only so that some deep debugging
can be done - which would not be useful for someone not used to the base
code.
Now that you have highlighted, I will see if we can entirely remove
those non-documented toggles.

+ This is not a DPAA specific configuration - it is a generic RTE config.
+ For optimal performance and hardware utilization, it is expected that DPAA
+ Mempool driver is used for mempools. For that, this configuration needs to
+ enabled.
+
+Environment Variables
+~~~~~~~~~~~~~~~~~~~~~
+
+DPAA drivers uses the following environment variables to configure its
+state during application initialization:
+
+- ``DPAA_NUM_RX_QUEUES`` (default 1)
Why not getting this value as device arg?
We had this discussion during DPAA2 as well. This time, I was not sure
of how the device argument patches are turning out to be after the
re-shuffle being done by Gaetan. So, I kept this as it is.
