fc4bfea596 net/bnxt: fix Rx queue start/stop for Thor based NICs
Controller-specific handling is required for Thor-based NICs when
stopping or starting a receive queue, otherwise packet reception
may not be reliably resumed when a stopped receive queue is
restarted:
  - The VNIC default receive ring needs to be recomputed when a
    receive queue is stopped or started.
  - When stopping the last (or only) receive queue for a given
    VNIC, ensure that no packets can reach the default receive
    ring by temporarily setting the VNIC MRU to zero.

67678ec076 net/bnxt: release HWRM lock before returning
The function bnxt_vnic_rss_configure_thor() returns early when
all receive queues are stopped without releasing the hwrm
spinlock, which causes subsequent HWRM operations to hang. Fix
by ensuring that the lock is released before returning from
this function.

34a068411a net/bnxt: fix RSS table update for start/stop Rx queue
A previous commit made updating of the RSS table when a receive
queue is stopped/started conditional on vnic->rx_queue_cnt being
nonzero. This count is only nonzero for dynamically created VNICs,
so the RSS table was not being updated in the normal path.
Fix by restoring the original logic.

Also ensure that vnic->rx_queue_cnt is initialized to zero when
reinitializing the VNIC array.

90bdf7956c net/bnxt: fix initialization
During initialization sequence in bnxt_alloc_mem()
if bnxt_alloc_async_cp_ring() fails, driver invokes bnxt_free_mem()
which in turn call bnxt_free_vnic_mem() which causes the error logs
"bnxt_free_vnic_mem(): VNIC is not freed yet!". This is because
vnic memory is allocated but not initialized yet.

Fix this by moving bnxt_init_vnics() from bnxt_init_nic() to
bnxt_alloc_vnic_mem(). Also get rid of bnxt_init_nic() as the
initialization is done in respective functions now.

8937597cfe net/bnxt: fix crash after removing and adding slaves
On removing the slave interface, slave_remove in bonding module calls
_rte_eth_dev_reset which in turn frees both Tx and Rx queues.
1. segfault is seen after removing/adding the slave interface and starting
bond interface.
In this below path, when mtu is set for the slave interface, queues are
not created yet and driver reference to queue[0] causes the segfault.
slave_configure:
	rte_eth_dev_set_mtu
	rte_eth_dev_configure
	rte_eth_rx_queue_setup

2. segfault is seen on starting the port after removing from bond device.
This is a testpmd bug where in, on starting the port, testpmd is supposed
to recreate the queues before starting the port.

Fixed these by adding check for queues created before accessing them.

5bee7bef8d net/bnxt: fix handling interface change status
Driver issues hwrm_if_change when the port is started and stopped.
This command returns whether the fw has undergone a reset while port
was down. Fix to handle hwrm_if_change status during port start only.

e0d865357e net/bnxt: enable interrupts according interface status
Driver issues hwrm_if_change when the port is started. This command
returns whether the fw has undergone a reset while port was down and
driver does re-init of resources if fw has undergone a reset.
Fix to enable interrupts only after this check.

8a82aef190 net/bnxt: change MSI-X vector to queue mapping
DPDK PCIe-VFIO framework configures base MSIX vector for interrupts
which is supported by other h/w. In case of bnxt, base MSIX vector
starts with the RX completion queue 0. To comply with the DPDK
framework We need to increase the map index by 1 so that RXTX
completion queues events can be delivered to appropriate event listeners
by kernel VFIO.

458f0360e8 net/bnxt: get default HWRM command timeout from FW
The HWRM command timeout is set to a very high value.
VER_GET command response returns the default request timeout value.
Use this value for waiting for HWRM commands to complete.
Poll for the valid bit every 1us instead of 600us.
