972bf36106 ethdev: fix shallow copy of flow API RSS action
The rss_conf field is defined as a pointer to struct rte_eth_rss_conf.

Even assuming it is permanently allocated and a pointer copy is safe,
pointed data may change and not reflect an applied flow rule anymore.

This patch aligns with testpmd by making a deep copy instead.

4b954bb167 ethdev: remove new to old offloads API helpers
According to

commit 315ee8374e0e ("doc: reduce initial offload API rework scope
		     to drivers")

All PMDs should have moved to the new offloads API. Therefore it is safe
to remove the new->old convert helps.

The old->new helpers will remain to support application which still use
the old API.

ea2dc10668 vfio: add multi container support
This patch adds APIs to support container create/destroy and device
bind/unbind with a container. It also provides API for IOMMU programing
on a specified container.

A driver could use "rte_vfio_container_create" helper to create a new
container from eal, use "rte_vfio_container_group_bind" to bind a device
to the newly created container. During rte_vfio_setup_device the container
bound with the device will be used for IOMMU setup.

340b7bb8d5 vfio: extend data structure for multi container
Currently eal vfio framework binds vfio group fd to the default
container fd during rte_vfio_setup_device, while in some cases,
e.g. vDPA (vhost data path acceleration), we want to put vfio group
to a separate container and program IOMMU via this container.

This patch extends the vfio_config structure to contain per-container
user_mem_maps and defines an array of vfio_config. The next patch will
base on this to add container API.

fcntl() for unlocking the file. Disregarding the fact that error
value returned from fcntl() unlock call is highly unlikely in the

7f0bb634a1 log: add ability to match log type with globbing
Regular expressions are not the best way to match a hierarchical
pattern like dynamic log levels. And the separator for dynamic
log levels is period which is the regex wildcard character.

A better solution is to use filename matching 'globbing' so
that log levels match like file paths. For compatibility,
use colon to separate pattern match style arguments. For
example:
	--log-level 'pmd.net.virtio.*:debug'

This also makes the documentation match what really happens
internally.

2ed9bf3307 eal: abstract away the auxiliary vector
Rather than attempting to load the contents of the auxv directly,
prefer to use an exposed API - and if that doesn't exist then attempt
to load the vector.  This is because on some systems, when a user
is downgraded, the /proc/self/auxv file retains the old ownership
and permissions.  The original method of /proc/self/auxv is retained.

This also removes a potential abort() in the code when compiled with
NDEBUG.  A quick parse of the code shows that many (if not all) of
the CPU flag parsing isn't used internally, so it should be okay.

With the new hotplug functionality having better standing, new usage

allow to rationalize this part of the EAL and ensure that fewer memory
