13d3780df6 net/bnxt: fix default Rx queue for Thor
Use first receive queue assigned to VNIC as the default receive queue
when configuring Thor VNICs. This is necessary e.g. in order for flow
redirection to a specific receive queue to work correctly.

74721ba062 net/bnxt: fix stats context calculation
The required number of statistics contexts is computed as the sum
of the number of receive and transmit rings plus one for the async
completion ring. A statistics context is not actually required for
the async completion ring, so remove it from the calculation.

84d49664b5 net/bnxt: support CoS classification
Class of Service (CoS) is a way to manage multiple types of
traffic over a network to offer different types of services
to applications. CoS classification (priority to cosqueue) is
determined by the user and configured through the PF driver.
DPDK driver queries this configuration and maps the cos queue
ids to different VNICs. This patch adds this support.

6118503d80 net/bnxt: fix VLAN filtering
Currently, when hw-vlan-filter is enabled on testpmd, driver is
receiving all vlan packets. Instead, it should only receive untagged
packets and vlan packets for which the VLAN filter is programmed.
This is because, the default rule to match on MAC is not getting
deleted, when hw-vlan-filter is ON.

This patch fixes the problem, by deleting the default MAC rule and
programming a new rule to receive only untagged packets, when
hw-vlan-filter is enabled & another rule for each vlan, as and when
that vlan is configured on that port.

3955e26870 net/bnxt: fix Rx queue start/stop
Driver should not change "deferred_start" state of the rx queues.
It should get the state in queue_setup_op() and use that value.

Since the deferred start state was being used in the packet receive
functions to determine whether a stopped rx ring should be polled,
introduced a per-rxq flag to track queue stopped/started state.

09aac391a5 net/bnxt: fix forwarding with higher mbuf size
Maximum frame length supported by hw is 9600 bytes.
When user launches testpmd with --mbuf-size=9729,
we are posting buffer descriptors of size 9601 to the ring.
This was causing packets getting discarded.

d43fe8ea0c net/bnxt: fix flow steering
When user creates a flow similar to an existing flow with just the
destination queue change, we delete the old filter and allocate a new
one with this destination queue change. We were also allocating a new L2
filter matching the same destination mac resulting in 2 L2 filters for the
same destination mac.
This was causing any flow matching the destination mac to be steered to
this queue instead of the default queue.

Fixed it by deleting this stale L2 filter.

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.

70b8062e85 net/bnxt: avoid null pointer dereference
Commit "bd0a14c99f65" enables the creation of a dedicated completion
ring for asynchronous event handling instead of handling these
events on a receive completion ring on non Stingray Platforms.

This causes a segfault due to NULL pointer dereference in
bnxt_alloc_async_cp_ring() on stingray. Fix this by checking the
pointer validity before accessing it.

"Using rte_mem_virt2iova()" during load.

Reduce the verbosity of logs to DEBUG. Reduced couple of other
