eal: add function to release internal resources
This commit adds a new function rte_eal_cleanup().
The function serves as a hook to allow DPDK to release
internal resources (e.g.: hugepage allocations).
This function allows DPDK to become more like an ordinary
library, where the library context itself can be initialized
and cleaned up by the application.
The rte_exit() and rte_panic() functions must be considered,
particularly if they should call rte_eal_cleanup() to release any
resources or not. This patch adds the cleanup to rte_exit(),
but does not clean up on rte_panic(). The reason to not clean
up on panicing is that the developer may wish to inspect the
exact internal state of EAL and hugepages.

net/tap: implement RSS using eBPF
TAP PMD is required to support RSS queue mapping based on rte_flow API. An
example usage for this requirement is failsafe transparent switching from a
PCI device to TAP device while keep redirecting packets to the same RSS
queues on both devices.
TAP RSS implementation is based on eBPF programs sent to Linux kernel
through BPF system calls and using netlink messages to reference the
programs as part of traffic control commands.
TC uses eBPF programs as classifiers and actions.
eBPF classification: packets marked with an RSS queue will be directed
to this queue using TC with "skbedit" action.
BPF classifiers are downloaded to the kernel once on TAP creation for
each TAP Rx queue.
eBPF action: calculate the Toeplitz RSS hash based on L3 addresses and
L4 ports. Mark the packet with the RSS queue according the resulting
RSS hash, then reclassify the packet.
BPF actions are downloaded to the kernel for each new RSS rule.
TAP eBPF requires Linux version 4.9 configured with BPF. TAP PMD will
successfully compile on systems with old or non-BPF configured kernels but
RSS rules creation on TAP devices will not be successful

Although granularity of chunks in a mempool is a cacheline, addresses are

registering a MR (Memory Region). This could make some regions overlap,
then can cause Tx completion error due to incorrect LKEY search. If the

as a thin configuration layer that automatically instantiates and controls
fail-safe PMD instances combining tap and PCI sub-devices, so that each
NetVSC interface is exposed as a single consolidated port to DPDK
applications.
PCI sub-devices being hot-pluggable (e.g. during VM migration),
applications automatically benefit from increased throughput when present
and automatic fallback on NetVSC otherwise without interruption thanks to
fail-safe's hot-plug handling.
Once initialized, the sole job of the vdev_netvsc driver is to regularly
scan for PCI devices to associate with NetVSC interfaces and feed their
addresses to corresponding fail-safe instances.

vhost: do deep copy while reallocating queue
When vhost reallocate dev and vq for NUMA enabled case, it doesn't perform
deep copy, which lead to 1) zmbuf list not valid 2) remote memory access.
This patch is to re-initlize the zmbuf list and also do the deep copy.

net/mrvl: allow adding MAC address before port init
Since DPDK restores ether address configuration after device
is started it is safe to add ether address to uninitialized port (ppio).

net/mrvl: allow changing MTU before port init
DPDK updates MTU once mtu_set() callback returns success.
Since PMD changes port's MTU to dev->mtu every time device is
started it is safe to call mtu_set() before MUSDK ppio was initialized.

net/sfc: convert to new Tx offload API
Ethdev Tx offloads API has changed since:
commit
cba7f53b717d ("ethdev: introduce Tx queue offloads API")
This commit support the new Tx offloads API.
The code which fills in txq_flags in default_txconf is preserved
because rte_eth_dev_info_get() lacks conversion between offloads
and txq_flags fields which means that a legacy application which
relies on default_txconf will fail to configure Tx queues in the
case when some bits in txq_flags are mandatory.

ethdev: add function to look up Tx offload names
Commonly, drivers converted to the new offload API
may need to log unsupported offloads as a response
to wrong settings. From this perspective, it would
be convenient to have generic functions to look up
