The code is very similar, but the simple case can skip a few branches
in the hot path. This improves PPS when 10KB mbufs are used.
S/G is enabled on the Rx side by offload DEV_RX_OFFLOAD_SCATTER.
S/G is enabled on the Tx side by offload DEV_TX_OFFLOAD_MULTI_SEGS.
S/G is automatically enabled on the Rx side if the provided mbufs are
too small to hold the maximum possible frame.
To enable S/G in testpmd, add these args:
--rx-offloads=0x2000 --tx-offloads=0x8000

When 'ionic_cmb' is set to '1', queue memory will be allocated from
the device's onboard memory (Controller Memory Buffer). In some

Commit 5be3b40fea ("net/bonding: fix values of descriptor limits")
breaks reporting of "nb_min" and "nb_align" values obtained from
back-end devices' descriptor limits. This means that work done
by eth_bond_slave_inherit_desc_lim_first() as well as
eth_bond_slave_inherit_desc_lim_next() gets dismissed.
Revert the offending commit and use proper workaround
for the test case mentioned in the said commit.
Meanwhile, the test case itself might be poorly constructed.
It tries to run a bond with no back-end devices attached,
but, according to [1] ("Requirements / Limitations"),
at least one back-end device must be attached.

setting the flow. Because device should be started to set the flow.

Some PMDs (e.g. hns3) could detect hardware or firmware errors, one
error recovery mode is to report RTE_ETH_EVENT_INTR_RESET event, and
wait for application invoke rte_eth_dev_reset() to recover the port,
however, this mode has the following weaknesses:
1) Due to different hardware and software design, some NIC port recovery
process requires multiple handshakes with the firmware and PF (when the
port is VF). It takes a long time to complete the entire operation for
one port, If multiple ports (for example, multiple VFs of a PF) are
reset at the same time, other VFs may fail to be reset. (Because the
reset processing is serial, the previous VFs must be processed before
the subsequent VFs).
2) The impact on the application layer is great, and it should stop
working queues, stop calling Rx and Tx functions, and then call
rte_eth_dev_reset(), and re-setup all again.
This patch introduces proactive error handling mode, the PMD will try
to recover from the errors itself. In this process, the PMD sets the
data path pointers to dummy functions (which will prevent the crash),
and also make sure the control path operations failed with retcode
-EBUSY.
Because the PMD recovers automatically, the application can only sense
that the data flow is disconnected for a while and the control API
returns an error in this period.
In order to sense the error happening/recovering, three events were
introduced:
1) RTE_ETH_EVENT_ERR_RECOVERING: used to notify the application that it
detected an error and the recovery is being started. Upon receiving the
event, the application should not invoke any control path APIs until
receiving RTE_ETH_EVENT_RECOVERY_SUCCESS or
RTE_ETH_EVENT_RECOVERY_FAILED event.
2) RTE_ETH_EVENT_RECOVERY_SUCCESS: used to notify the application that
it recovers successful from the error, the PMD already re-configures the
port, and the effect is the same as that of the restart operation.
3) RTE_ETH_EVENT_RECOVERY_FAILED: used to notify the application that it
recovers failed from the error, the port should not usable anymore. The
application should close the port.

Currently, the defined error handling modes include:

2) PASSIVE: passive error handling, after the PMD detect that a reset
is required, the PMD reports RTE_ETH_EVENT_INTR_RESET event, and
application invoke rte_eth_dev_reset() to recover the port.

Save some cpu time and disk by testing linking against static and shared
library in single environments.
The .ci/linux-build.sh is modified so it reconfigures an existing build
directory: an empty DEF_LIB= means that static and shared builds are
to be tested.
ABI checks, documentation generation and unit tests are disabled for
static builds as they would be redundant with the check against
dynamically linked binaries, if any.
Note:
- --cross-file is an option that can be passed to meson only when
creating a build environment,
- for some other reason, --buildtype and other non -D options are only
accepted when setting up a build directory with meson. When
reconfiguring, only their -D$option forms are accepted,
