b9c9416790 bus/dpaa: decouple FQ portal alloc and init
The decoupling of FQ portal allocation is required as a
pre-requisite to support Rx interrupts as we need to have
event FD's at portal allocation i.e. before the
initialization of the Frame Queues.
This change will help us get the event fd once the portals
have been allocated for static FQ's.

c46c7a7161 net/bnxt: support for QinQ insertion and stripping
Driver will accelerate only outer/S-VLAN insertion by turning on
the appropriate bits in the Tx Buffer Descriptor when the packet
arrives for transmission.
The TPID to be used for this S-VLAN is conveyed by the vlan_tpid_set
dev_op which will terminate in the driver.
In the Rx path, driver will continue providing the stripped vlan tag
in the mbuf's vlan tci field. This would be the outermost vlan tag
in a double-tagged packet or the vlan tag for a single vlan tagged pkt.

6cbd89f9f3 net/bnxt: support PTP for Thor
On Thor, direct access to PTP registers (via GRC) is not supported.
Driver must use HWRM to access the timestamp information.

Vectorized Rx/Tx cannot be enabled if RTE_LIBRTE_IEEE1588=y.
Remove the PTP flags handling code from the vector Rx path.

Add support to read tx timestamp value and the time from the
timesync clock.

On Thor, Rx timestamps are provided directly in the Rx completion
records to the driver. Only 32 bits of the timestamp is present in
the completion. Driver needs to read the current 48 bit free running
timer using the HWRM_PORT_TS_QUERY command and combine the upper
16 bits from the HWRM response with the lower 32 bits in the
Rx completion to produce the 48 bit timestamp for the Rx packet.

f836242401 net/bnxt: query firmware error recovery capabilities
In Driver initiated error recovery process, driver has to know about
the registers offset and values to initiate FW reset. The HWRM command
HWRM_ERROR_RECOVERY_QCFG is used to obtain all the registers and values
required to initiate FW reset. This command response includes
FW heart_beat register, health status register, Error counter register,
register offsets and values to do chip reset if firmware crashes and
becomes unresponsive.

2e88b08391 net/bnxt: handle fatal event from FW
When firmware hit some unrecoverable error conditions, firmware initiate
the recovery by sending an async event EVENT_CMPL_EVENT_ID_RESET_NOTIFY
with data1 set to RESET_NOTIFY_EVENT_DATA1_REASON_CODE_FW_EXCEPTION_FATAL
to all host drivers and will reset the chip.

The recovery procedure is same sequence as the one for hot FW upgrade.

0b53359123 net/bnxt: inform firmware about IF state changes
Use latest firmware API to inform firmware about IF state changes.
Firmware has the option to clean up resources during IF down and
to require the driver to reserve resources again during IF up.

During port start, HWRM_FUNC_DRV_IF_CHANGE command response
flags indicates that firmware has reset. Add logic to re-probe
the firmware and re-setup resources.

df6cd7c1f7 net/bnxt: handle reset notify async event from FW
When the FW upgrade is initiated the current instance
of FW issues a HWRM_ASYNC_EVENT_CMPL_EVENT_ID_RESET_NOTIFY
async notification to the driver. On receiving this notification,
the PMD shall quiesce itself and poll on the HWRM_VER_GET FW
command at regular intervals.

Once the VER_GET command succeeds, the driver should go through
the rediscovery process and re-initialize the device.

Also register with FW for the reset notify async event.

1bf01f5135 net/bnxt: prevent device access when device is in reset
Refactor init and uninit functions so that the driver can fail
the eth_dev_ops callbacks and accessing Tx and Rx queues
when device is in reset or in error state.

Transmit and receive queues are freed during reset cleanup and
reallocated during recovery. So we block all data path handling
in this state. The eth_dev dev_started field is updated depending
on the status of the device.

92d5dd4834 net/mlx5: check sibling device configurations mismatch
The devices backed by mlx5 PMD might share the same multiport
Infiniband device context. It regards representors and slaves
of bonding device. These ports are spawned with devargs.
These patch check whether configuration deduced from these
devargs is compatible with configurations if devices
sharing the same context. It prevents the incorrect
whitelists, like:

-w 82:00.0,representor=0,dv_flow_en=1
-w 82:00.0,representor=1,dv_flow_en=0

The representors with indices [0-1] are supposed to spawned
over the same PCi device, but there is dv_flow_en parameter
mismatch.
