4cfe399f65 net/bnxt: support to set VF rxmode
This patch adds support to configure the VF L2 Rx settings.
The per VF setting is maintained in bnxt_child_vf_info.l2_rx_mask

0958d8b643 net/bnxt: support LRO
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.

daef48efe5 net/bnxt: support set MTU
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.

2bb1d5db43 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
some reformatting to perform a graceful cleanup in case memory
allocation fails.

2eb53b134a 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.

57d5e5bc86 net/bnxt: add statistics
Add the bnxt_stats_get_op() and bnxt_stats_reset_op() dev_ops to
get and reset statistics. It also brings in the associated HWRM calls
to handle the requests appropriately.

We also have the bnxt_free_stats() function which will be used in the
follow on patches to free the memory allocated by the driver for
statistics.

New HWRM calls:
bnxt_hwrm_stat_clear:
	This command clears statistics of a context

6133f20797 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.

We are also adding hwrm_vnic_rss_cfg_* structures, which will be used
in subsequent patches to enable RSS configuration.
