87520e59fb net/bnxt: fix freeing filters on flow creation failure
This patch does following things:
1. Added a wrapper function bnxt_clear_one_vnic_filter()
   for destroying the filters in hw. This will avoid duplicate
   code in many places.
2. When flow create fails due to an already existing mark id
   for the new flow id created, fixed to destroy the hw
   filter created.
3. Re-arranged code to move a log and list update to right place.

f456684ac2 net/bnxt: fix unnecessary HWRM command
During probe, driver issues HWRM_CFA_ADV_FLOW_MGNT_QCAPS command.
But it is not using the command response anywhere which makes the
fw call redundant.

Remove the unnecessary HWRM_CFA_ADV_FLOW_MGNT_QCAPS call to fw.
Remove the redundant flow_flags in bnxt struct.

0466d286cd net/bnxt: fix setting link speed
bnxt PMD uses the macro BNXT_SUPPORTED_SPEEDS to validate
the user requested speed. But this has all the speed values
supported by the PMD and is not chip specific.

The check against this macro returns success when the user

not support 100G speed.

Fixed it to use bnxt_get_speed_capabilities() to check the
supported speeds by the chip.

02a95625fe net/bnxt: add flow stats in extended stats
This patch allows to display flow stats in extended stats.
To do this, DMA-able memory is registered with the FW during device
initialization. Then the driver uses an alarm thread to query the
per flow stats using the HWRM_CFA_COUNTER_QSTATS HWRM command at
regular intervals and stores it locally which will be displayed
when the application queries the xstats.
The DMA-able memory is unregistered during driver cleanup.
This functionality can be enabled using the flow-xstat devarg and
will be disabled by default. The intention behind this is to allow
stats to be displayed for all the flows in one shot instead of
querying one at a time.

f0f6b5e6cf net/bnxt: fix reusing L2 filter
The software L2 filter was being released back to the free pool,
though it was created in HW and the filter corresponding to an actual
'flow' would have reference to the HW L2 filter.
But if this 'flow were to be deleted, then this HW L2 filter also
would be gone.
Fix this by storing the L2 filter created originally either for an
n-tuple flow or otherwise as part of the vnic's filter list.
This would require the filter_info struct to have a backptr to the
vnic which it came from.
Now that L2 filters can be re-used for an n-tuple filter(s), delete
L2 filter as well so the reference count of an L2 filter (if reused)
can be decremented appropriately.

41a9d881cb net/bnxt: fix jumbo frame configuration in firmware
In order to prevent reconfiguration of firmware resources for every
MTU change, configure FW with max MTU value using hwrm_func_cfg
to support all frame sizes. There is no need to overwrite the driver
level MTU variable data->mtu with the FW MTU.

89a0deb866 net/bnxt: fix resource qcaps with older FW
On some old versions of FW, bnxt_hwrm_func_resc_qcaps can return an
error. This is because the command was not implemented completely
in FW till the subsequent version. Ignore the error and continue with
the driver initialization.

fc4bfea596 net/bnxt: fix Rx queue start/stop for Thor based NICs
Controller-specific handling is required for Thor-based NICs when
stopping or starting a receive queue, otherwise packet reception
may not be reliably resumed when a stopped receive queue is
restarted:
  - The VNIC default receive ring needs to be recomputed when a
    receive queue is stopped or started.
  - When stopping the last (or only) receive queue for a given
    VNIC, ensure that no packets can reach the default receive
    ring by temporarily setting the VNIC MRU to zero.

67678ec076 net/bnxt: release HWRM lock before returning
The function bnxt_vnic_rss_configure_thor() returns early when
all receive queues are stopped without releasing the hwrm
spinlock, which causes subsequent HWRM operations to hang. Fix
by ensuring that the lock is released before returning from
this function.

938a87db43 net/bnxt: fix redundant MAC address check
filter->mac_index is used to check, if a same mac is
already programmed. Hence, filter->dflt member is not
needed which is also used for mac addr redundancy check.

This patch fixes it by moving mac_index based redundant
check from bnxt_mac_addr_add_op to bnxt_add_mac_filter
