e97f83e452 ethdev: replace snprintf with strlcpy for owner
The set_port_owner was copying a string between structures of the
same type, therefore the name could never be truncated (unless source
string was not null terminated).  Use strlcpy which does it better.

The patch fix this issue by setting the same value as 40G, this

027412fe94 net/nfp: fix setting MAC address
Some firmwares, mostly for VFs, do not advertise the feature /
capability of changing the MAC address while the interface is up. With
such firmware a request to change the MAC address that at the same
time also tries to enable the not available feature will be denied by
the firmware resulting in an error message like:

nfp_net_reconfig(): Error nfp_net reconfig for ctrl: 80000000 update: 800

Fix set_mac_addr by not trying to enable a feature if it is not
advertised by the firmware.

b89f6deb86 net/i40e: update queue number check for rounding
Since rounding up the requested queue pairs to allow the VF to
request a non-aligned number was added, it may happen that the
requested number is less than the available num of queues but the
rounded up number is greater. In this case, it is not caught with
the usual checks but later when there is a reset and failed setup.

By rounding earlier the checks can be done before a failed reset
occurs, and a rounded max amount of available queues can be returned
to the VF.

a7cece2ead malloc: add NUMA-aware realloc function
Currently, rte_realloc will not respect original allocation's
NUMA node when memory cannot be resized, and there is no
NUMA-aware equivalent of rte_realloc. This patch adds such a function.

The new API will ensure that reallocated memory stays on
requested NUMA node, as well as allow moving allocated memory
to a different NUMA node.

218c4e68c1 mk: use linux and freebsd in config names
Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e.  both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"

4445a0f4c7 net/enic: fix inner packet matching
Inner packet matching is currently buggy in many cases.

1. Mishandling null spec ("match any").
The copy_item functions do nothing if spec is null. This is incorrect,
as all patterns should be appended to the L5 pattern buffer even for
null spec (treated as all zeros).

2. Accessing null spec causing segfault.

3. Not setting protocol fields.
The NIC filter API currently has no flags for "match inner IPv4, IPv6,
UDP, TCP, and so on". So, the driver needs to explicitly set EtherType
and IP protocol fields in the L5 pattern buffer to avoid false
positives (e.g. reporting IPv6 as IPv4).

Instead of keep adding "if inner, do something differently" cases to
the existing copy_item functions, introduce separate functions for
inner packet patterns and address the above issues in those
functions. The changes to the previous outer-packet copy_item
functions are mechanical, due to reduced indentation.

d7316eae1a net/enic: fix VXLAN match
The filter API does not have flags for "match VXLAN". Explicitly set
the UDP destination port and mask in the L4 pattern. Otherwise, UDP
packets with non-VXLAN ports may be falsely reported as VXLAN.

1400 series VIC adapters have hardware VXLAN parsing. The L5 buffer on
the NIC starts with the inner Ethernet header, and the VXLAN header is
now in the L4 buffer following the UDP header. So the VXLAN spec/mask
needs to be in the L4 pattern, not L5. Older models still expect the
VXLAN spec/mask in the L5 pattern. Fix up the L4/L5 patterns
accordingly.

477959e6ee net/enic: enable limited support for raw flow item
Some apps like VPP use a raw item to match UDP tunnel headers like
VXLAN or GENEVE. The NIC hardware supports such usage via L5 match,
which does pattern match on packet data immediately following the
outer L4 header. Accept raw items for these limited use cases.

60c6acb43d net/enic: move arguments into struct
There are many copy_item functions, all with the same arguments, which
makes it difficult to add/change arguments. Move the arguments into a
struct to help subsequent commits that will add/fix features. Also
remove self-explanatory verbose comments for these local functions.

These changes are purely mechanical and have no impact on
functionalities.

5af7af4d6b net/enic: enable limited passthru flow action
Some apps like VPP use PASSTHRU+MARK flow rules to offload packet
matching to the NIC. Just like MARK+RSS used by OVS-DPDK and others,
PASSTHRU+MARK is used to "mark and then receive normally". Recent VIC
adapters support such flow rules, so enable PASSTHRU for this limited
use case.

e9434f6f60 net/enic: enable limited RSS flow action
Some apps like OVS-DPDK use MARK+RSS flow rules in order to offload
packet matching to the NIC. The RSS action in such flow rules simply
indicates "receive packet normally", not trying to override the port
wide RSS. The action is included in the flow rules simply to terminate
them, as MARK is not a fate-deciding action. And, the RSS action has a
most basic config: default hash, level, types, null key, and identity
queue mapping.

Recent VIC adapters can support these "mark and receive" flow
rules. So, enable support for RSS action for this limited use case.

4d8e9aa483 net/enic: check for unsupported flow item types
Currently a pattern with an unsupported item type causes segfault,
because the flow handler is using the type as an array index without
checking bounds. Add an explicit check for unsupported item types and
avoid out-of-bound accesses.
