net/bonding: allow external state machine in mode 4

Provide functions to allow an external 802.3ad state machine to transmit
and receive LACPDUs and to set the collection/distribution flags on
slave interfaces.

net/bonding: inherit maximum Rx packet length

Instead of a hard-coded maximum receive length, allow the bonded interface
to inherit this limit from the slave interfaces.  This allows
an application that uses jumbo frames to pass realistic values to
rte_eth_dev_configure without causing an error.

Before the bonding interface is configured, allow slaves with any
max_rx_pktlen to be added and remember the lowest of these values as
a candidate value.  During dev_configure, set the bond device's
max_rx_pktlen to the candidate value.  After this point only slaves
with a max_rx_pktlen greater or equal to that of the bonding device
can be added.

If all slaves are removed, the bond device's pktlen is cleared.

net/fm10k: fix promiscuous receive for VF

When app tries to change promisc/allmulti setting, fm10k will check if a
valid glort is acquired, and exit without doing anything if not.

For VFs, this glort value is not necessary, and so the check can be
removed. This saves having unnecessary failures of the API call, as well as
saving the time taken for the mailbox communication between VF and PF in
the case when the glort check passes.

net/bnxt: allocate Rx/Tx and completion rings

Perform allocation and free()ing of ring and information structures
for the TX, RX, and completion rings. The previous patches had
so far provided top level stubs and generic ring support, while this
patch does the real allocation and freeing of the memory specific to
each different type of generic ring.

For example bnxt_init_tx_ring_struct() or bnxt_init_rx_ring_struct() is
now allocating memory based on the socked_id being provided.

bnxt_tx_queue_setup_op() or bnxt_rx_queue_setup_op() have gone through

net/bnxt: add initial Rx code

This patch adds initial implementation of rx_pkt_burst() function for Rx.
bnxt_recv_pkts() is the top level function for doing Rx.

This patch also adds code to allocate rings in the ASIC.

For each Rx queue allocated in the PMD driver, a corresponding ring
in hardware will be created. Every time a frame is received a Rx ring
is selected based on the hardware configuration like RSS, MAC or VLAN,
COS and such. The hardware uses a completion ring to indicate the
availability of a packet.

This patch also brings in functions like bnxt_init_one_rx_ring()
bnxt_init_rx_ring_struct() which initializes various structures before
a Rx can begin.

bnxt_init_rxbds() initializes the Rx Buffer Descriptors while
bnxt_alloc_rx_data() allocates a buffer in the host to receive the
incoming packet.

net/bnxt: add initial Tx code

Initial implementation of tx_pkt_burst for transmit.

bnxt_handle_tx_cp() is used to check and process the Tx completions
generated for the Tx Buffer Descriptors sent by the hardware.

This patch also adds code to allocate rings in the hardware.
For each Tx queue allocated in the PMD driver, a corresponding ring
in hardware will be created. Every time a Tx request is initiated
via the bnxt_xmit_pkts() call, a Buffer Descriptor is created and
is sent to the hardware via the associated Tx ring.

On completing the Tx operation, the hardware will generates the status
in the form of a completion. This completion is processed by the
bnxt_handle_tx_cp() function.

Functions like bnxt_init_tx_ring_struct() and bnxt_init_one_tx_ring()
are used to initialize various members of the structure before
starting Tx operations.

net/bnxt: add Rx queue create/destroy

In this patch we are adding the bnxt_rx_queue_setup_op() and
bnxt_rx_queue_release_op() functions. These will be tied to the
rx_queue_setup and rx_queue_release dev_ops in a subsequent patch.
In these functions we allocate/free memory for the RX queues.

This still requires support to create a RX ring in the ASIC which
will be completed in a future commit. Each Rx queue created via the
rx_queue_setup dev_op will have an associated Rx ring in the hardware.

The Rx logic in the hardware picks a Rx ring for each Rx frame received
by the hardware depending on the properties like RSS, MAC and VLAN
settings configured in the hardware. These packets in the end arrive
on the Rx queue corresponding to the Rx ring in the hardware.

We are also adding some functions like bnxt_mq_rx_configure()
bnxt_free_rx_mbufs() and bnxt_free_rxq_stats() which will be used in
subsequent patches.
