01fa83c94d net/af_xdp: workaround custom program loading
Since v0.4.0, if the underlying kernel supports it, libbpf uses 'bpf
link' to manage the programs on the interfaces of the XDP sockets (xsks).
This is not compatible with the PMD's custom XDP program loading feature
which uses the netlink-based method for loading custom programs.

The conflict arises when libbpf searches for a custom program on the
interface using bpf link, but doesn't find one because the netlink
method was used. libbpf then proceeds to try to load the default program
on the interface, but fails due to the presence of the custom program.

To work around this, the PMD now uses the
XSK_LIBBPF_FLAGS__INHIBIT_PROG_LOAD flag which prevents libbpf from
attempting to search for or load a program. One repercussion is that
DPDK must now insert the xsk into the xsks_map as this was previously
handled by libbpf during the routines for program loading/probing.

Ideally, the PMD would use bpf link to load the custom program, however
at present there is no convenient and reliable way of detecting whether
the underlying kernel supports bpf link. Perhaps this may become
available in a future libbpf release, at which point we can switch the
PMD over to the new bpf link based method.

9f394004c3 net/af_xdp: revert use BPF link for XDP programs
The commit ae70cc6e89 ("net/af_xdp: use BPF link for XDP programs")
caused compilation errors on kernels older than v5.8 due to absence of
the bpf_link_info struct and some definitions in the linux/bpf.h header.
Since relying on the reported kernel version is not a robust solution
and also since there doesn't appear to be a suitable definition in the
bpf header that the preprocessor could rely on to determine support for
bpf link, we will take a different approach to solving the issue that
the original patch attempted to solve. The next commit will address
this.

ce78c51833 net/mlx5: fix delay drop bit set overflow
The attribute to record the global control of hairpin queues' delay
drop was defined as a bit-field with one bit, and the intention was
to reduce the memory overhead. In the meanwhile, the macro was
defined as an enumerated value 0x2.

No matter what value inputted via devarg, the lowest bit was always
zero and the higher bits would be ignored. For hairpin queues, the
delay drop attribute couldn't be enabled.

With the commit, the double logical negation is used to fix this.

Rx descriptor is 16B/32B in size. If the DD bit is set, it indicates
that the rest of the descriptor words have valid values. Hence, the
word containing DD bit must be read first before reading the rest of
the descriptor words.

Since the entire descriptor is not read atomically, on relaxed memory
ordered systems like Aarch64, read of the word containing DD field
could be reordered after read of other words.

Read barrier is inserted between read of the word with DD field
and read of other words. The barrier ensures that the fetched data
is correct.

On ThunderX2, 22% performance regression was observed.

9143a09ded net/ice: fix adminq handling on DCF passive reset
DCF tries to handle AdminQ when DCF is reset by PF, however the invalid
data may be returned, and error log may be output in this situation.

This patch stops handling AdminQ when a passive reset is detected to
avoid this situation.

1a3709c1f0 doc: describe timestamp limitations for mlx5
The ConnectX NIC series hardware provides only 63-bit
wide timestamps. The imposed limitations description
added to documentation.

At the moment there are no affected applications known
or bug reports neither, this is just the declaration
of limitation.

e53d873dc0 net/mlx5: fix modify field action conversion
The routine converting RTE flow modify field action into
field driver's presentation did not specify the field mask
correctly and this resulted into wrong conversion for
the actions with shifted fields.

8594e2a64f common/mlx5: fix build for zero-length headroom array
The structure of the striding RQ(MPRQ) buffer includes an array size
defined by the RTE_PKTMBUF_HEADROOM macro added in [1].

When RTE_PKTMBUF_HEADROOM is set to 0 in the compilation config file
the compilation with debug type failed:

"In file included from ../drivers/common/mlx5/mlx5_common.h:25,
                 from ../drivers/common/mlx5/linux/mlx5_nl.h:12,
                 from ../drivers/common/mlx5/linux/mlx5_nl.c:22:
../drivers/common/mlx5/mlx5_common_mr.h:96:10: error: ISO C forbids
                             zero-size array 'pad' [-Werror=pedantic]"

Actually, the array for the first stride headroom is not needed:

Each stride in the striding RQ buffer includes the headroom of the next
stride, so the headroom of the first stride should be allocated before
the starting point of the buffer posted to the HW(HW buffer).

The striding RQ buffer is used as an attached buffer to mbuf and have
shared information per stride.

The LRO support moved all the strides shared information to the top of
the buffer before the first stride headroom but didn't remove the old
memory of this headroom from the buffer.

Remove the old headroom memory from the striding RQ buffer.

6b5b3005cb net/mlx5: fix RETA update without stopping device
The global redirection table is used to create the default flow
rules for the ingress traffic with the lowest priority. It is also
used to create the default RSS rule in the destination table when
there is a tunnel offload.

To update the RETA in-flight, there is no restriction in the ethdev
API. In the previous implementation of mlx5, a port restart was
needed to make the new configuration take effect.

The restart is heavy, e.g., all the queues will be released and
reallocated, users' rules will be flushed. Since the restart is
internal, there is a risk to crash the application when some change
in the ethdev is introduced but no workaround is done in mlx5 PMD.

The users' rules, including the default miss rule for tunnel
offload, should not be impacted by the RETA update. It is improper
to flush all rules when updating RETA.

With this patch, only the default rules will be flushed and
re-created with the new table configuration.

a9b6ea45be net/mlx5: fix tag ID conflict with sample action
For the flows containing sample action, the tag action was added
implicitly to store the unique flow index into metadata register in the
split prefix subflow, and then match on this index in the split suffix
subflow. The metadata register for flow index of sample split subflows
was also used to store application metadata TAG 0 item, this might cause
TAG 0 corruption in the flows with sample actions.

This patch uses the same metadata register C index as used for
ASO action since it's reserved and not used directly by the application,
and adds the checking in validation to make sure not to conflict
with ASO CT in the same flow.

aaa6a7ec0f net/mlx5: fix tunnel offload validation
Tunnel offload API allows the application to restore packet to
its original form if the chain of flows is missed after DECAP action.

MLX5 PMD provides tunnel offload support only if DV API was enabled.

The patch verifies DV availability before processing with
tunnel offload tasks.
