Current mlx4 OFED version has bug which returns error to
ibv destroy functions when the device was plugged out, in
spite of the resources were destroyed correctly.
Hence, failsafe PMD was aborted, only in debug mode, when
it tries to remove the device in plug-out process.
The workaround added option to replace all claim_zero
assertions with debugging messages, by the way, this option
affects non ibv destroy assertions.
DPDK 18.02 release should work with Mellanox OFED-4.2 which will
include the verbs fix to this bug, then, this patch can

Introduce the fail-safe poll mode driver initialization and enable its
build infrastructure.
This PMD allows for applications to benefit from true hot-plugging
support without having to implement it.
It intercepts and manages Ethernet device removal events issued by
slave PMDs and re-initializes them transparently when brought back.
It also allows defining a contingency to the removal of a device, by
designating a fail-over device that will take on transmitting operations
if the preferred device is removed.
Applications only see a fail-safe instance, without caring for
underlying activity ensuring their continued operations.

Introducing the DEV_TX_OFFLOAD_MT_LOCKFREE TX capability flag.
if a PMD advertises DEV_TX_OFFLOAD_MT_LOCKFREE capable, multiple threads
can invoke rte_eth_tx_burst() concurrently on the same tx queue without
SW lock. This PMD feature will be useful in the following use cases and
found in the OCTEON family of NPUs.
1) Remove explicit spinlock in some applications where lcores
to TX queues are not mapped 1:1.
example: OVS has such instance
https://github.com/openvswitch/ovs/blob/master/lib/netdev-dpdk.c#L299https://github.com/openvswitch/ovs/blob/master/lib/netdev-dpdk.c#L1859
See the the usage of tx_lock spinlock.
2) In the eventdev use case, avoid dedicating a separate TX core for
transmitting and thus enables more scaling as all workers can
send the packets.

To support frames > 2k, the PMD creates an aggregator ring.

1) For a VF, query the firmware to determine if a MAC address is
already configured. If not configure a random default MAC address.
2) Do not initialize the default completion ring in
bnxt_alloc_hwrm_rings().
3) While registering for async events with the firmware,
use func_vf_cfg for a VF and use func_cfg for a PF.
4) Query the VNIC plcmode config using the bnxt_hwrm_vnic_plcmodes_qcfg
before a VNIC is updated. Reconfigure the VNIC with the plcmode
configuration queried earlier. Not doing this could overwrite
the plcmodes in some cases.
5) Reorg the bnxt_handle_fwd_req to properly handle the forwarded
requests. The previous code did not handle it completely.

TX coalescing waits for ETH_COALESCE_PKT_NUM packets to be coalesced
across bursts before transmitting them. For slow traffic, such as
100 PPS, this approach increases latency since packets are received
one at a time and tx coalescing has to wait for ETH_COALESCE_PKT
number of packets to arrive before transmitting.
To fix this:
- Update rx path to use status page instead and only receive packets
when either the ingress interrupt timer threshold (5 us) or
the ingress interrupt packet count threshold (32 packets) fires.
(i.e. whichever happens first).
- If number of packets coalesced is <= number of packets sent
by tx burst function, stop coalescing and transmit these packets
immediately.
Also added compile time option to favor throughput over latency by
default.
