[PATCH 1/2] net/bonding: standard the log message

[Chaoyong He]

From: Long Wu <long.wu@corigine.com>

According to the check rules in the patch check script,
drivers and libraries must use the logging framework.

[PATCH 2/2] net/bonding: add command to set dedicated queue size

[Chaoyong He]

From: Long Wu <long.wu@corigine.com>

The testpmd application can not modify the value of
dedicated hardware Rx/Tx queue size, and hardcoded
them as (128/512). This will cause the bonding port
start fail if some NIC requires more Rx/Tx descriptors
than the hardcoded number.

Therefore, add a command into testpmd application to
support the modification of the size of the dedicated
hardware Rx/Tx queue. Also export an external interface
to also let other applications can change it.

This is confusing.
The patch goes to all the effort to configure rx_queue_size but it is
never actually used in the driver.

We do used it in the function 'member_configure_slow_queue()' of file 'drivers/net/bonding/rte_eth_bond_pmd.c'.

The original logic hardcodes the value of dedicated hardware Rx/Tx queue size into (128/512) and this will cause the
bonding port start fail if the NIC requires more Rx/Tx descriptors than the hardcoded number.

And this is the situation for our NFP card:
```
testpmd> port stop all
testpmd> create bonding device 4 0
testpmd> set bonding balance_xmit_policy 2 l34
testpmd> add bonding member 0 2
testpmd> add bonding member 1 2
testpmd> set bonding lacp dedicated_queues 2 enable
testpmd> show bonding config 2
testpmd> port start 2
Configuring Port 2 (socket 0)
ETHDEV: Device with port_id=0 already stopped
ETHDEV: Device with port_id=1 already stopped
ETHDEV: Device with port_id=0 already stopped
ETHDEV: Invalid value for nb_rx_desc(=128), should be: <= 32768, >= 512, and a product of 128
member_configure_slow_queue(1699) - rte_eth_rx_queue_setup: port=0 queue_id 1, err (-22)
ETHDEV: Device with port_id=1 already stopped
ETHDEV: Invalid value for nb_rx_desc(=128), should be: <= 32768, >= 512, and a product of 128
member_configure_slow_queue(1699) - rte_eth_rx_queue_setup: port=1 queue_id 1, err (-22)
Port 2: 88:3C:C5:A0:32:46
Checking link statuses...
Done
```

And if apply this patch and configure the 'rx_queue_size', then we can start the bonding port successfully.

[PATCH 0/2] add function to set dedicated queue size

[Chaoyong He]

This patch series mainly add a function to bonding PMD to set
dedicated queue size, also add a command to testpmd application
to invoke this function.

At the same time, standard the log message of bonding PMD.

Long Wu (2):
  net/bonding: standard the log message
  net/bonding: add command to set dedicated queue size
