Listen to INTR_RMV events issued by slaves.
Add atomic flags on slave queues to detect use of slave bursts function.
If a removal is detected, set the recollection flag on this slave.
During a slave upkeep round, if its recollection flag is set and its
burst functions are not in use by any thread, remove that slave.

Add the "exec" device type.
The parameters given to this type of device will be executed in a shell.
The output of this command is then used as a definition for a device.
That command can be re-interpreted if the related device is not
plugged-in. It allows for a device definition to react to system
changes (e.g. changing PCI bus for a given device).

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.

This patch adds support to enable and disable LRO
To support this feature, the driver creates an aggregator ring.
When the hardware starts doing LRO, it sends a tpa_start completion.
When the driver receives a tpa_end completion, it indicates that the
LRO chaining is complete.

This patch adds support to modify MTU using the set_mtu dev_op.
To support frames > 2k, the PMD creates an aggregator ring.
When a frame greater than 2k is received, it is fragmented
and the resulting fragments are DMA'ed to the aggregator ring.
Now the driver can support jumbo frames upto 9500 bytes.

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.
