810b17d116 ethdev: allow unknown link speed
When querying the link information, the link status is
a mandatory major information.
Other boolean values are supposed to be accurate:
	- duplex mode (half/full)
	- negotiation (auto/fixed)

This API update is making explicit that the link speed information
is optional.
The value ETH_SPEED_NUM_NONE (0) was already part of the API.
The value ETH_SPEED_NUM_UNKNOWN (infinite) is added to cover
two different cases:
	- speed is not known by the driver
	- device is virtual

a6f67a3b64 net: optimize ethernet address functions
* rte_is_broadcast_ether_addr():
Use binary logic instead of comparisons and boolean logic, thus reducing
the number of branches.
It now resembles rte_is_zero_ether_addr().

* rte_ether_addr_copy():
The source code modifications were discussed on the mailing list:
http://mails.dpdk.org/archives/dev/2020-June/171584.html
Remove obsolete ICC-specific code and related comment.
Restrict pointer aliasing (suggested by Jerin Jacob).
Remove superfluous "Fast" from function description headline; all DPDK
data plane functions are supposed to be fast.

8929de043e service: retrieve lcore active state
This commit adds a new experimental API which allows the user
to retrieve the active state of an lcore. Knowing when the service
lcore is completed its polling loop can be useful to applications
to avoid race conditions when e.g. finalizing statistics.

The service thread itself now has a variable to indicate if its
thread is active. When zero the service thread has completed its
service, and has returned from the service_runner_func() function.

e1ece60956 pci: move resource mapping to the PCI bus
As reported during 20.08 work for Windows, the pci_map_resource API was
built with the assumption that its flags would be passed to mmap().

This introduced a regression when adding the rte_mem_map API as reported
in the workaround commit 9d2b245937 ("pci: keep API compatibility with
mmap values").

This API was only used in the PCI bus code, so move it there.

There is no code change happening during the move.
The only change is in the pci_map_resource description where the
additional flags are now documented as rte_mem_map API flags:
- *      The additional flags for the mapping range.
+ *      The additional rte_mem_map() flags for the mapping range.

819a716858 vhost: fix async callback return type
The async copy device callbacks are used by async APIs to transfer data
and check completion status. Async APIs return the number of packets
successfully processed to the caller applications and no error
(negative) value is allowed for API return value. Thus, negative return
values from async device callbacks don't have meaningful usage, while
adding overhead in checking the return value validity. This patch change
the callback return values from "int" to "uint32_t" to get aligned with
async API definition.

9dbe628a7b mempool: fix allocation in memzone during retry
If allocation is successful on the first attempt, typically
there is no problem since we allocated everything required and
we'll terminate the loop (if memory chunk is really sufficient
to populate required number of mempool elements).

If the first attempt fails, we try to allocate half
of mem_size and it succeed, we'll have one more iteration of
the for-loop to allocate memory for remaining elements and
should not try the next time with quarter of the mem_size.

It is wrong that max_alloc_size is divided by 2 in the
case of successful allocation as well, or invalid memory
can be allocated, and leads to population failure, then errno
other than ENOMEM may be returned.

5b2655a693 node: add packet classifier
This node classifies pkts based on packet type and
sends them to appropriate next node. This is node
helps in distribution of packets from ethdev_rx node
to different next node with a constant overhead for
all packet types.

Currently all except non fragmented IPV4 packets are marked
to be sent to "pkt_drop" node.
Performance difference on ARM64 Octeontx2 is -4.9% due to
addition of new node in the path.
