58bb1ee4a5 net/qede/base: update FW to 8.40.33.0
In our testing we have identified a critical FW bug. Performance
is degraded significantly for certain packet sizes with 8.40.25.0 FW.

This patch updates the FW to version 8.40.33.0. The updated FW has a
fix to performance issue.

The patch also adds initialization for FW overlay RAM as part of
hardware initialization which is required by the new FW.

8de0c42019 net/qede: fix odd number of queues usage in 100G mode
As per HW design of 100Gb mode, device internally uses 2 engines
(eng0 and eng1), and both engines need to be configured symmetrically.
Based on this requirement, driver design chose an approach
to allow user to allocate only even number of queues and split
those queues on both engines equally.

This approach puts a limitation on number of queues to be allocated -
i.e. user can't configure odd number of queues on 100Gb mode.
OVS configures DPDK port with 1 rxq and 1 txq, which causes initialization
of qede port to fail.

Issue is fixed by changing the implementation of queue allocation and
assignment to hw engines only for 100Gb devices and allowing user to
configure odd number queues.

New approach works as below -
- Create 'struct qede_fastpath_cmt' to hold hw queue pair of both engines
  and provide it to rte_ethdev's Rx/Tx queues structure.
- So ethdev will see only one queue for underlying queue pair created for
  hw engine pair.
- Install separate Rx/Tx data path handlers for 100Gb mode and regular mode
- Rx/Tx handlers for 100Gb mode will split packet processing across both
  engines by providing hw queue structures from 'struct qede_fastpath_cmt'
  passed by Rx/Tx callbacks to respective engines.

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.

f4be6a9a29 fix off-by-one errors in snprintf
snprintf guarantees to always correctly place a null terminator
in the buffer string. So manually placing a null terminator
in a buffer right after a call to snprintf is redundant code.

Additionally, there is no need to use 'sizeof(buffer) - 1' in snprintf as this
means we are not using the last character in the buffer. 'sizeof(buffer)' is
enough.

3732f83a45 net/qede: fix Rx packet drop
There is a corner case in which driver won't post
receive buffers when driver has processed all received packets
in single loop (i.e. hw_consumer == sw_consumer) and then
HW will start dropping packets since it did not see new receive
buffers posted.

This corner case is seen when size of Rx ring is less than or equals

7aac5899df net/qede: support IOVA VA mode
Set RTE_PCI_DRV_IOVA_AS_VA in drv_flags. This allows initializing qede
PMD as non-root also on Linux v4.x, where /proc/self/pagemap can't be
acccessed without CAP_SYS_ADMIN privileges.

The flag was introduced generically but not in pmds in:
commit 815c7deaed ("pci: get IOMMU class on Linux")

902f389f9b drivers/net: fix shifting 32-bit signed variable 31 times
Shifting signed 32-bit values by 31-bits has the potential for
unexpected  outcomes as compiler can overwrite a bit.

60f9a63457 net/qede: fix Tx packet prepare for tunnel packets
This patch fixes a regression introduced by
commit 49d3978d57 ("net/qede: fix Tx tunnel offload support mask")
in which qede_xmit_prep_pkts() breaks the loop for successful
check of Tunneling offload flags instead of continuing, resulting
in tx_pkt_prepare return a failure.

8f23124745 net/qede: fix performance bottleneck in Rx path
Allocating replacement buffer per received packet is expensive.
Instead, process received packets first and allocate
replacement buffers in bulk later.

This improves performance by ~25% in terms of PPS on AMD
platforms.

3985ea528a net/qede: fix Tx offload mask
Following commit updated the Tx offload mask
commit 1037ed842c ("mbuf: fix Tx offload mask").

So, not having PKT_TX_IPV6 and PKT_TX_IPV4 in qede PMDs supported
Tx offload mask breaks TSO support since application will fail in transmit
prepare function.

49d3978d57 net/qede: fix Tx tunnel offload support mask
Tunneling offloads are represented by multi-bit values. So, feature
wise tunneling offload can only be entirely supported/unsupported
using PKT_TX_TUNNEL_MASK. Its upon PMDs to further isolate which of
the tunneling offload types are supported by respective PMD.
Using subset of bits from PKT_TX_TUNNEL_MASK to indicate supported vs
unsupported offloads can lead to undesired result.

Use PKT_TX_TUNNEL_MASK in QEDE_TX_OFFLOAD_MASK and use independent
value of supported PKT_TX_TUNNEL_* in .tx_pkt_prepare() to mark
supported tunnel offloads.

69d3e963e4 net/qede: fix crash when configure fails
Currently, if configuration fails (for example if a 100G card is used
with an odd number of RX/TX queues) QEDE crashes due to a null pointer
dereference.

This commit fixes it by checking that the pointer is not NULL before
using it.
