Invoke bnxt_get_unused_filter() inside bnxt_alloc_filter() so that
all filters are allocated from one common routine.

Now that the L2 filter reference count is bumped up in all cases
including bnxt_alloc_filter() which is issued in init, just move this
ref count bump inside the routine issuing the HWRM cmd so that it is
bumped up only if the cmd is successful.

Allow RSS action with group ID 0. The RSS match check will ensure if
requested RSS action configuration parameters should be allowed as per
the VNIC's RSS configuration or not and if it does match as it is
by design in OVS-DPDK use case, the default vnic can be used to create
the filter. As part of this ensure that rx_queue_cnt for the default
vnic is setup during init as this field was being set only for non-zero
vnics while handling RSS action for flow create.
Check for outofboundds erorr while accessing the vnic array.

Since "eth_dev->data->dev_started" has been assigned to 0 at the
beginning of bnxt_dev_stop_op() routine, the code inside the if()
condition is redundant. Remove it.

Anyways "eth_dev->data->dev_link.link_status" will be set to 0 in
bnxt_dev_set_link_down_op() later in the routine.

Fixes: 316e412299fd ("net/bnxt: fix crash when closing")

Use "dev->data->dev_started" state, instead of local BNXT_FLAG_INIT_DONE
to check whether device has been initialised or not.

This change could help in reducing the size of bnxt PMD private
data structure by converting a uint8_t variable to use bit map flag.

Use "dev->data->dev_started" state, instead of local "dev_stopped"
to check whether port has been started or not.

Certain applications(Ex: OVS-DPDK) can issue rte_flow_create with mark id
set to 0. The mark table entry creation in the driver was assuming
non-zero mark ids. Fix it to have a valid flag for each entry.
Also, it is possible that both RSS flags and cfa_code/ mark id are
set as part of the Rx packet completion descriptor if the 'action'
for a flow is MARK + RSS.
Fix Rx completion processing to look for both fields as opposed to
only either.

Fixes: 94eb699bc82e ("net/bnxt: support flow mark action")

Invoke bnxt_get_unused_filter() inside bnxt_alloc_filter() so that
all filters are allocated from one common routine.

Now that the L2 filter reference count is bumped up in all cases
including bnxt_alloc_filter() which is issued in init, just move this
ref count bump inside the routine issuing the HWRM cmd so that it is
bumped up only if the cmd is successful.

From: Somnath Kotur <somnath.kotur@broadcom.com>

Allow RSS action with group ID 0. The RSS match check will ensure if
requested RSS action configuration parameters should be allowed as per
the VNIC's RSS configuration or not and if it does match as it is
by design in OVS-DPDK use case, the default vnic can be used to create
the filter. As part of this ensure that rx_queue_cnt for the default
vnic is setup during init as this field was being set only for non-zero
vnics while handling RSS action for flow create.
Check for outofboundds erorr while accessing the vnic array.

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

Since "eth_dev->data->dev_started" has been assigned to 0 at the
beginning of bnxt_dev_stop_op() routine, the code inside the if()
condition is redundant. Remove it.

Anyways "eth_dev->data->dev_link.link_status" will be set to 0 in
bnxt_dev_set_link_down_op() later in the routine.

Use "dev->data->dev_started" state, instead of local "dev_stopped"
to check whether port has been started or not.

From: Somnath Kotur <somnath.kotur@broadcom.com>

Certain applications(Ex: OVS-DPDK) can issue rte_flow_create with mark id
set to 0. The mark table entry creation in the driver was assuming
non-zero mark ids. Fix it to have a valid flag for each entry.
Also, it is possible that both RSS flags and cfa_code/ mark id are
set as part of the Rx packet completion descriptor if the 'action'
for a flow is MARK + RSS.
Fix Rx completion processing to look for both fields as opposed to
only either.

Fixes: 94eb699bc82e ("net/bnxt: support flow mark action")

Hi Kalesh,

The patch title doesn't really say much, it should say the actual reason not
just fixing a tools warning, I am updating it as:

"net/bnxt: fix return value check"

Also the defined syntax for Coverity issues is:
Coverity issue: ####

For this case it should be:
Coverity issue: 353621
