21b1677d87 net/bnxt: refactor multi-queue Rx configuration
Eliminate separate codepath/handling for single queue
as the multiqueue code path takes care of it as well.
The only difference being the end_grp_id being 1
now instead of 0 for single queue, but that does not matter
for single queue and does not alter any functionality.

6aba4a036e net/bnxt: skip get statistics for stopped queues
An application using rte_flow may define a large number of queues
but only use a small subset of them at any one time.

Since querying the status of each queue requires a request/spin/reply
with the firmware, optimize by skipping the request for queues not
running.
For those queues the statistics will be 0.

This cuts the cost of single xstats query in half and has even
bigger gain for simple stats query.

  zero, 'fw_version' being NULL but 'fw_size' not zero condition checked
  in ethdev layer
* Be sure required buffer size is returned if provided one is not big
  enough, instead of returning success (0)
* Document in doxygen comment the '-EINVAL' is a valid return type
* Take into account that 'snprintf' can return negative value

d723d1fe5d net/bnxt: fix health check alarm cancellation
Driver cancels the health check alarm only if error recovery is enabled
in the FW. This can cause an issue. There is a small window where the
driver receives the async event from FW and port close is invoked
immediately. Driver clears BNXT_FLAG_RECOVERY_ENABLED flag when it gets
the async event from FW. As a result, the health check alarm will not
get canceled during port close and causes a segfault when the alarm tries
to read Heartbeat register.

Fix this by canceling the health check alarm unconditionally during
port stop.

During port start when bnxt_start_nic() fails, it tries to free
"intr_handle->intr_vec" but the variable is not set to NULL after that.
If port start fails, driver invokes bnxt_dev_stop() which will lead

4fb6ab3f86 net/bnxt: check flush status during ring free
When host SW issues a HWRM_RING_FREE for Tx/Rx/AGG ring in HW,
the FW flushes the BDs associated with the ring and performs other
cleanup in the HW. The host software should ideally check for an
indication from the FW indicating this step has been completed
successfully to avoid unexpected errors during cleanup.

The FW issues a HWRM_DONE response to the RING_FREE request on
the corresponding CQ ring. Poll the CQs during cleanup and
ensure the HWRM_FREE command is completed not just based on the
value of valid bit but also the HWRM_DONE response for the ring.

If the HWRM_DONE response is not seen, force the cleanup to
complete just based on the valid bit.

   - Correct misinterpretation of offset parameter as ring index.
   - Correct misuse of completion ring index for mbuf ring (the

53f98141ee net/bnxt: fix PTP support for Thor
On Thor, Rx timestamp is present in the Rx completion record.
Only 32 bits of the timestamp is present in the completion.
The driver needs to periodically poll the current 48 bit
free running timer using the HWRM_PORT_TS_QUERY command.
It can 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.

This patch adds an alarm thread to periodically poll the current 48 bit
free running timer using the HWRM_PORT_TS_QUERY command.
This avoids issuing the hwrm command from the Rx handler.
This patch also handles the timer roll over condition.

6a4f7139cb net/bnxt: fix FW readiness check during recovery
Moved fw readiness check to a new routine bnxt_check_fw_ready().

During error recovery, driver needs to wait for fw readiness.
For that, it uses bnxt_hwrm_ver_get() function now and that
function does parsing of the VER_GET response as well.

Added a new lightweight function bnxt_hwrm_poll_ver_get() for polling
the firmware readiness which issues VER_GET and checks for success
without processing the command response.

94131e4ab7 net/bnxt: fix firmware fatal error handling
During some fatal firmware error conditions, the PCI config space
register 0x2e which normally contains the subsystem ID will become
0xffff. This register will revert back to the normal value after
the chip has completed core reset. If we detect this condition,
we can poll this config register immediately for the value to revert.
Because we use config read cycles to poll this register, there is no
possibility of Master Abort if we happen to read it during core reset.
This speeds up recovery significantly as we don't have to wait for the
conservative min_time before polling to see if the firmware has come
out of reset. As soon as this register changes value we can proceed
to re-initialize the device.

705e0f32f6 net/bnxt: handle echo request async message
This is a new async message that the firmware can send to check if it
can communicate with the driver. This is an added error detection
scheme that firmware can use if it suspects errors in the PCIe
interface. When the driver receives this async message, it will reply
back echoing some data in the async message. If the firmware is not
getting the reply with the proper data after some retries, error
recovery will kick in.

c23190303e net/bnxt: fix queues per VNIC
Update queues per VNIC in single queue mode.
bp->rx_num_qs_per_vnic is not initialized in the single queue mode.
As a result of this when an interface is reconfigured to single
queue mode from an existing multiqueue mode, bp->rx_num_qs_per_vnic
is not updated to the value of 1. Hence, the driver will try to
access more than one queue resulting in a crash.

This patch fixes it by initializing bp->rx_num_qs_per_vnic in the
single queue mode as well.
