3.5 Overriding Configuration for Special Cases
----------------------------------------------
When using the bonding driver, the physical port which transmits a frame is
typically selected by the bonding driver, and is not relevant to the user or
system administrator. The output port is simply selected using the policies of
the selected bonding mode. On occasion however, it is helpful to direct certain
classes of traffic to certain physical interfaces on output to implement
slightly more complex policies. For example, to reach a web server over a
bonded interface in which eth0 connects to a private network, while eth1
connects via a public network, it may be desirous to bias the bond to send said
traffic over eth0 first, using eth1 only as a fall back, while all other traffic
can safely be sent over either interface. Such configurations may be achieved
using the traffic control utilities inherent in linux.
4. Querying Bonding Configuration
By default the bonding driver is multiqueue aware and 16 queues are created
when the driver initializes (see Documentation/networking/multiqueue.txt
for details). If more or less queues are desired the module parameter
tx_queues can be used to change this value. There is no sysfs parameter
available as the allocation is done at module init time.
The output of the file /proc/net/bonding/bondX has changed so the output Queue
ID is now printed for each slave:
Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: eth0
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0
Slave Interface: eth0
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:1a:a0:12:8f:cb
Slave queue ID: 0
Slave Interface: eth1
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:1a:a0:12:8f:cc
Slave queue ID: 2
The queue_id for a slave can be set using the command:
# echo "eth1:2" > /sys/class/net/bond0/bonding/queue_id
Any interface that needs a queue_id set should set it with multiple calls
like the one above until proper priorities are set for all interfaces. On
distributions that allow configuration via initscripts, multiple 'queue_id'
arguments can be added to BONDING_OPTS to set all needed slave queues.
These queue id's can be used in conjunction with the tc utility to configure
a multiqueue qdisc and filters to bias certain traffic to transmit on certain
slave devices. For instance, say we wanted, in the above configuration to
force all traffic bound to 192.168.1.100 to use eth1 in the bond as its output
device. The following commands would accomplish this:
# tc qdisc add dev bond0 handle 1 root multiq
# tc filter add dev bond0 protocol ip parent 1: prio 1 u32 match ip dst \
192.168.1.100 action skbedit queue_mapping 2
These commands tell the kernel to attach a multiqueue queue discipline to the
bond0 interface and filter traffic enqueued to it, such that packets with a dst
ip of 192.168.1.100 have their output queue mapping value overwritten to 2.
This value is then passed into the driver, causing the normal output path
selection policy to be overridden, selecting instead qid 2, which maps to eth1.
Note that qid values begin at 1. Qid 0 is reserved to initiate to the driver
that normal output policy selection should take place. One benefit to simply
leaving the qid for a slave to 0 is the multiqueue awareness in the bonding
driver that is now present. This awareness allows tc filters to be placed on
slave devices as well as bond devices and the bonding driver will simply act as
a pass-through for selecting output queues on the slave device rather than
output port selection.
This feature first appeared in bonding driver version 3.7.0 and support for
output slave selection was limited to round-robin and active-backup modes.

retval = poll(&pfd, 1, timeout);
-------------------------------------------------------------------------------
+ PACKET_TIMESTAMP
-------------------------------------------------------------------------------
The PACKET_TIMESTAMP setting determines the source of the timestamp in
the packet meta information. If your NIC is capable of timestamping
packets in hardware, you can request those hardware timestamps to used.
Note: you may need to enable the generation of hardware timestamps with
SIOCSHWTSTAMP.
PACKET_TIMESTAMP accepts the same integer bit field as
SO_TIMESTAMPING. However, only the SOF_TIMESTAMPING_SYS_HARDWARE
and SOF_TIMESTAMPING_RAW_HARDWARE values are recognized by
PACKET_TIMESTAMP. SOF_TIMESTAMPING_SYS_HARDWARE takes precedence over
SOF_TIMESTAMPING_RAW_HARDWARE if both bits are set.
int req = 0;
req |= SOF_TIMESTAMPING_SYS_HARDWARE;
setsockopt(fd, SOL_PACKET, PACKET_TIMESTAMP, (void *) &req, sizeof(req))
If PACKET_TIMESTAMP is not set, a software timestamp generated inside
the networking stack is used (the behavior before this setting was added).
See include/linux/net_tstamp.h and Documentation/networking/timestamping
for more information on hardware timestamps.
