This patch removes a redundant assert in mlx5_tx_packet_multi_tso().
That assert assured that the amount of bytes requested to be inlined
is greater than or equal to the minimum amount of bytes required
to be inlined. This requirement is either derived from the NIC
inlining mode or configured through devargs. When using TSO this
requirement can be disregarded, because on all NICs it is satisfied by
TSO inlining requirements, since TSO requires L2, L3, and L4 headers to
be inlined.
Meter capabilities reporting is not up to date.

MPRQ cannot be used in multi-process applications because of

a primary process to free MPRQ buffers once they are no longer
needed. But this information is shared among all the processes.
The virtual address of the mlx5_mprq_buf_free_cb function is
different in a secondary process, which leads to a segmentation

ethdev: introduce IP reassembly offload
IP Reassembly is a costly operation if it is done in software.
The operation becomes even more costlier if IP fragments are encrypted.
However, if it is offloaded to HW, it can considerably save application
cycles.
Hence, a new offload feature is exposed in eth_dev ops for devices which
can attempt IP reassembly of packets in hardware.
- rte_eth_ip_reassembly_capability_get() - to get the maximum values
of reassembly configuration which can be set.
- rte_eth_ip_reassembly_conf_set() - to set IP reassembly configuration
and to enable the feature in the PMD (to be called before
rte_eth_dev_start()).
- rte_eth_ip_reassembly_conf_get() - to get the current configuration
set in PMD.
Now when the offload is enabled using rte_eth_ip_reassembly_conf_set(),
the resulting reassembled IP packet would be a typical segmented mbuf in
case of success.
And if reassembly of IP fragments is failed or is incomplete (if
fragments do not come before the reass_timeout, overlap, etc), the mbuf
dynamic flags can be updated by the PMD. This is updated in a subsequent
patch.

Secondly, entries in a context's indirection table are not precise
queue IDs but offsets with regard to the base queue ID of a filter.
This way, for example, queue arrays "0, 1, 2" and "3, 4, 5" in two
otherwise identical RSS specifications allow the driver to use the
same context since they both yield the same table of queue offsets.
Rework flow action RSS support in order to use these optimisations.

When a tap device is hotplugged to primary process which in turn
adds the device to all secondary process, the secondary process
does a tap_mp_attach_queues, but the fds are not populated in

added a fix to sync the queues during rte_eth_dev_start

net/af_xdp: use libxdp if available
AF_XDP support is deprecated in libbpf since v0.7.0 [1]. The libxdp library
now provides the functionality which once was in libbpf and which the
AF_XDP PMD relies on. This commit updates the AF_XDP meson build to use the
libxdp library if a version >= v1.2.2 is available. If it is not available,
only versions of libbpf prior to v0.7.0 are allowed, as they still contain
the required AF_XDP functionality.
libbpf still remains a dependency even if libxdp is present, as we use
libbpf APIs for program loading.
The minimum required kernel version for libxdp for use with AF_XDP is v5.3.
For the library to be fully-featured, a kernel v5.10 or newer is
recommended. The full compatibility information can be found in the libxdp
README.
v1.2.2 of libxdp includes an important fix required for linking with DPDK
which is why this version or greater is required. Meson uses pkg-config to
verify the version of libxdp on the system, so it is necessary that the
library is discoverable using pkg-config in order for the PMD to use it. To
verify this, you can run: pkg-config --modversion libxdp
The reason to the bug is that rte timer do not be cancelled when quit.
That is, in 'bond_ethdev_start', resources are allocated according to
different bonding mode. In 'bond_ethdev_stop', resources are free by
the corresponding mode.
For example, 'bond_ethdev_start' start bond_mode_8023ad_ext_periodic_cb
timer for bonding mode 4. and 'bond_ethdev_stop' cancel the timer only
when the current bonding mode is 4. If the bonding mode is changed,
and directly quit the process, the timer will still on, and freed memory
will be accessed, then segmentation fault.
'bonding mode' changed means resources changed, reallocate resources for
different mode should be done, that is, device should be restarted.

net/bonding: fix promiscuous and allmulticast state
Currently, promiscuous or allmulticast state of bonding port will not be
passed to the new primary slave when active/standby switch-over. It
causes bugs in some scenario.
For example, promiscuous state of bonding port is off now, primary slave
(called A) is off but secondary slave(called B) is on.
Then active/standby switch-over, promiscuous state of the bonding port
is off, but the new primary slave turns to be B and its promiscuous
state is still on.
It is not consistent with bonding port. And this patch will fix it.
