b02a39ba3b net/bnxt: fix extended port counter statistics
We were trying to fill in more rx extended stats than the size allocated
for stats causing segfault. Fixed this by adding an explicit check.
Rearranged the code to return statistic values in xstats_get as per the
names returned in xstats_get_names.

bd0a14c99f net/bnxt: use dedicated CPR for async events
This commit enables the creation of a dedicated completion
ring for asynchronous event handling instead of handling these
events on a receive completion ring.

For the stingray platform and other platforms needing tighter
control of resource utilization, we retain the ability to
process async events on a receive completion ring.

For Thor-based adapters, we use a dedicated NQ (notification
queue) ring for async events (async events can't currently
be received on a completion ring due to a firmware limitation).

Rename "def_cp_ring" to "async_cp_ring" to better reflect its
purpose (async event notifications) and to avoid confusion with
VNIC default receive completion rings.

Allow rxq 0 to be stopped when not being used for async events.

b4e190d55c net/bnxt: fix MAC/VLAN filter allocation
We were adding the VLAN filters to all the VNICs of the function.
Also, we were adding these VLANs to all the existing MAC only filters.
This was resulting in fewer VLANs getting added. By default we should
allocate MAC+VLAN filter only to the default VNIC of the function using
the default mac address.
Similar logic was followed in the VLAN deletion code. This patch fixes
it.  Use inner VLAN fields instead of outer VLAN during filter deletion
to be in sync with VLAN addition code.

3672b93dc4 net/bnxt: reset Rx allocation state on port restart
Move call site of bnxt_rxq_vec_setup() to ensure that rxq->rxrearm_nb
and rxq->rxrearm_start are reinitialized correctly when a port is
restarted.

72aaa312e9 net/bnxt: fix VF probe when MAC address is zero
VF driver should not fail probe if the host PF driver has not assigned
any MAC address for the VF. It should generate a random MAC address and
configure the MAC and then continue probing the device.

96b0931d51 net/bnxt: fix extended port counter statistics
1. refactor stats allocation code to new routine
2. check for extended statistics support depends on "hwrm_spec_code"
   which is set in bnxt_hwrm_ver_get called later. Hence we were never
   querying extended port stats as flags field was not updated. Fixed
   this by moving the stats allocation after the call to
   bnxt_hwrm_ver_get.
3. we were incorrectly passing the host address used for port
   statistics to PORT_QSTATS_EXT command. Fixed this by passing the
   correct extended stats address.

b76fafb174 eal: fix IOVA mode selection as VA for PCI drivers
The incriminated commit broke the use of RTE_PCI_DRV_IOVA_AS_VA which
was intended to mean "driver only supports VA" but had been understood
as "driver supports both PA and VA" by most net drivers and used to let
dpdk processes to run as non root (which do not have access to physical
addresses on recent kernels).

The check on physical addresses actually closed the gap for those
drivers. We don't need to mark them with RTE_PCI_DRV_IOVA_AS_VA and this
flag can retain its intended meaning.
Document explicitly its meaning.

We can check that a driver requirement wrt to IOVA mode is fulfilled
before trying to probe a device.

Finally, document the heuristic used to select the IOVA mode and hope
that we won't break it again.

b51690ec69 mbuf: clarify outer offsets for non-tunnel packets
The default policy for offload-specific fields is that
they are undefined unless the corresponding offloads are
requested in mbuf ol_flags. This is also the case for outer
L2 and L3 length fields which must not be assumed to contain
zeros for non-tunnel packets. The patch clarifies this behaviour
in the comments and also adds appropriate checks to the PMDs which
do not check any tunnel-related offloads before using the said fields.
