355b482e12 net/bnxt: move Tx bd checking to header file
To allow sharing of tx_bds_in_hw() and bnxt_tx_avail() between
vector-mode and non-vector transmit functions, move these functions
into bnxt_txr.h.

5897ac1393 net/mlx5: fix event handler uninstall
When device is being closed and tries to unregister interrupt callback,
there is a chance the handler is still active (called in context of
eal_intr_thread_main thread). If so the rte_intr_callback_unregister
returns -EAGAIN and keeps the handler registered, causing crash when
underlaying resourse is gone away.

This race condition may happen if event handling in application takes
a long time. We should check the return code of unregistering routine
and try again to unregister the handler. The diagnostic messages are
shown once a second, while trying to unregister.

0d51a5ec26 net/mlx5: fix order of items in NEON scatter
Previous patch added handling of metadata for multi-segment packet.
Function txq_scatter_v in file mlx5_rxtx_vec_neon.h was updated
incorrectly, items were inserted into WQE in wrong order.

This patch fixes the issue, inserting items into WQE correctly.

cd1dadeb9b examples/rxtx_callbacks: support HW timestamp
Use rxtx callback to demonstrate a way to use rte_eth_read_clock to
convert the hardware timestamps to an amount of cycles.

This allows to get the amount of time the packet spent since its entry
in the device. While the regular latency only shows the latency from
when it entered the software stack.

e571ad5541 net/mlx5: support reading clock
Implements support for read_clock for the mlx5 driver. mlx5 supports
hardware timestamp offload, setting packets timestamp field to the
device clock. rte_eth_read_clock allows to read the device's current
clock value and therefore compare values on similar time base.

See rxtx_callbacks for an example.

5e74137765 ethdev: add API to read device clock
Add rte_eth_read_clock to read the raw clock of a device.

The main use is to get the device clock conversion co-efficients to be
able to translate the raw clock of the timestamp field of the pkt mbuf
to a local synced time value.

This function was missing to allow users to convert the Rx timestamp
field to real time without the complexity of the rte_timesync* facility.
One can derivate the clock frequency by calling twice read_clock and
then keep a common time base.

64ac6feb82 bpf: fix pseudo calls for program loaded from ELF
clang 6.0 and onwards, for the external function call generates

e404de1305 config: disable armv8 crypto extension
Per armv8 crypto extension support, make build always enable it by default
as long as compiler supports the feature while meson build only enables it
for 'default' machine of generic armv8 architecture.

It is known that not all the armv8 platforms have the crypto extension. For
example, Mellanox BlueField has a variant which doesn't have it. If crypto
enabled binary runs on such a platform, rte_eal_init() fails.

'+crypto' flag currently implies only '+aes' and '+sha2' and enabling it
will generate the crypto instructions only when crypto intrinsics are used.
For the devices supporting 8.2 crypto or newer, compiler could generate
such instructions beyond intrinsics or asm code. For example, compiler can
generate 3-way exclusive OR instructions if sha3 is supported. However, it
has to be enabled by adding '+sha3' as of today.

In DPDK, armv8 cryptodev is the only one which requires the crypto support.
As it even uses external library of Marvell which is compiled out of DPDK
with crypto support and there's run-time check for required cpuflags,
crypto support can be disabled in DPDK.

69c06d0e35 net/mlx: support IOVA VA mode
Set RTE_PCI_DRV_IOVA_AS_VA to driver's drv_flags as device's IOMMU takes
virtual address.

0cb86518db bus/pci: add Mellanox kernel driver type
When checking RTE_PCI_DRV_IOVA_AS_VA flag to determine IOVA mode,
pci_one_device_has_iova_va() returns true only if kernel driver of the
device is vfio. However, Mellanox mlx4/5 PMD doesn't need to be detached
from kernel driver and attached to VFIO/UIO. Control path still goes
through the existing kernel driver, which is mlx4_core/mlx5_core. In order
to make RTE_PCI_DRV_IOVA_AS_VA effective for mlx4/mlx5 PMD, a new kernel
driver type has to be introduced.

ffadd933ac eal/x86: check rdrand and rdseed
The meson build never checked for the presence of rdrand and rdseed
instructions, while make build never checked for rdseed. Ensure builds
always have the appropriate checks - and therefore defines - for these
instructions. For runtime, we also add in rdseed to the list of known
bits returned from cpuid() instruction, so we can confirm its presence at
application init time.

a7c5f2606f config: shorten code for x86 instruction detection
Rather than checking flag by flag individually, use a loop to make it
easier to check new flags.
