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"
work.

The patch adds the PF counterpart changes to support VF promiscuous
mode by DPDK PF driver.

For ixgbe, in order to support VF VLAN promiscuous or unicast
promiscuous, PF need to set register PFVML2FLT of bit UPE and VPE.
The patch aligned to kernel driver's implementation.

it is printed using rte_hexdump().

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.

af3a16282a net/enic: reset VXLAN port regardless of overlay offload
Currently, the driver resets the vxlan port register only if overlay
offload is enabled. But, the register is actually tied to hardware
vxlan parsing, which is an independent feature and is always enabled
even if overlay offload is disabled. If left uninitialized, it can
affect flow rules that match vxlan. So always reset the port number
when HW vxlan parsing is available.

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

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.

e7347a8aff net/enic: allow flow mark ID 0
The driver currently accepts mark ID 0 but does not report it in
matching packet's mbuf. For example, the following testpmd command
succeeds. But, the mbuf of a matching IPv4 UDP packet does not have
PKT_RX_FDIR_ID set.

flow create 0 ingress pattern ... actions mark id 0 / queue index 0 / end

The problem has to do with mapping mark IDs (32-bit) to NIC filter
IDs. Filter ID is currently 16-bit, so values greater than 0xffff are
rejected. The firmware reserves filter ID 0 for filters that do not
mark (e.g. steer w/o mark). And, the driver reserves 0xffff for the
flag action. This leaves 1...0xfffe for app use.

It is possible to simply reject mark ID 0 as unsupported. But, 0 is
commonly used (e.g. OVS-DPDK and VPP). So, when adding a filter, set
filter ID = mark ID + 1 to support mark ID 0. The receive handler
subtracts 1 from filter ID to get back the original mark ID.

4182ee7f02 net/enic: fix flow director SCTP matching
The firmware filter API does not have flags indicating "match SCTP
packet". Instead, the driver needs to explicitly add an IP match and
set the protocol number (132 for SCTP) in the IP header.

The existing code (copy_fltr_v2) has two bugs.

1. It sets the protocol number (132) in the match value, but not the
mask. The mask remains 0, so the match becomes a wildcard match. The
NIC ends up matching all protocol numbers (i.e. thinks non-SCTP
packets are SCTP).

2. It modifies the input argument (rte_eth_fdir_input). The driver
tracks filters using rte_hash_{add,del}_key(input). So, addding
(RTE_ETH_FILTER_ADD) and deleting (RTE_ETH_FILTER_DELETE) must use the
same input argument for the same filter. But, overwriting the protocol
number while adding the filter breaks this assumption, and causes
delete operation to fail.

So, set the mask as well as protocol value. Do not modify the input
argument, and use const in function signatures to make the intention
clear. Also move a couple function declarations to enic_clsf.c from
enic.h as they are strictly local.

3ded348378 net/iavf: rename avf to iavf
Rename Intel Ethernet Adaptive Virtual Function driver avf to iavf.

This is the first patch which will only renames the directory name,
lib name, filenames and updates the new name in makefile and meson
files. Also updates the #include files in source files.

3ce6474b22 build: improve pcap dependency handling
pcap has historically shipped a custom pcap-config binary tool which
does the job of pkg-config. It was never compatible with cross
compilation.
Meson uses it when using dependency(), which then means cross
compilation fails.
Set pcap-config to empty in the meson cross compilation files so
that Meson will not use it, and add a fallback in case
dependency() fails.
libpcap 1.9.0 finally ships a pkg-config file so everything will
work out of the box in the future.

e30b4e566f build: improve dependency handling
Whenever possible (if the library ships a pkg-config file) use meson's
dependency() function to look for it, as it will automatically add it
to the Requires.private list if needed, to allow for static builds to
succeed for reverse dependencies of DPDK. Otherwise the recursive
dependencies are not parsed, and users doing static builds have to
resolve them manually by themselves.
When using this API avoid additional checks that are superfluous and
take extra time, and avoid adding the linker flag manually which causes
it to be duplicated.

d23e141ffa build: set RTE_ARCH_64 based on pointer size
Rather than relying on the target machine architecture, use the
size of a pointer from the compiler to determine if we are 64-bits
or not. This allows correct behaviour when you pass -m32 as a compile
option. It also allows us to use this value repeatedly throughout the
repo rather than continually testing for the sizeof(void*).

5c75a8efcd net/virtio: fix in-order Tx path for packed ring
When IN_ORDER feature is negotiated, device may just write out a
single used descriptor for a batch of buffers:

"""
Some devices always use descriptors in the same order in which they
have been made available. These devices can offer the VIRTIO_F_IN_ORDER
feature. If negotiated, this knowledge allows devices to notify the
use of a batch of buffers to the driver by only writing out a single
used descriptor with the Buffer ID corresponding to the last descriptor
in the batch.

The device then skips forward in the ring according to the size of the
batch. The driver needs to look up the used Buffer ID and calculate the
batch size to be able to advance to where the next used descriptor will
be written by the device.
"""

But the Tx path of packed ring can't handle this. With this patch,
when IN_ORDER is negotiated, driver will manage the IDs linearly,
look up the used buffer ID and advance to the next used descriptor
that will be written by the device.

e788032aac net/virtio: fix in-order Tx path for split ring
When IN_ORDER feature is negotiated, device may just write out a
single used ring entry for a batch of buffers:

"""
Some devices always use descriptors in the same order in which they
have been made available. These devices can offer the VIRTIO_F_IN_ORDER
feature. If negotiated, this knowledge allows devices to notify the
use of a batch of buffers to the driver by only writing out a single
used ring entry with the id corresponding to the head entry of the
descriptor chain describing the last buffer in the batch.

The device then skips forward in the ring according to the size of
the batch. Accordingly, it increments the used idx by the size of
the batch.

The driver needs to look up the used id and calculate the batch size
to be able to advance to where the next used ring entry will be written
by the device.
"""

Currently, the in-order Tx path in split ring can't handle this.
With this patch, driver will allocate desc_extra[] based on the
index in avail/used ring instead of the index in descriptor table.
And driver can just relay on the used->idx written by device to
reclaim the descriptors and Tx buffers.

7f949ae391 net/bonding: fix reset active slave
test_alb_reply_from_client test fails due to incorrect active slave
array's index. This was due to invalid active slave count.

Count of internals->active_slave is not updated even when active slave
is deactivated.
Hence active slave count always keeps incrementing beyond the actual
active slaves.

Fix is to set the internals->active_slave to starting index 0 whenever
it exceeds the number of slaves in active slave list and also update
the active slave count during slave de-activation.
