When the underlying device supports TCP offloads for VXLAN/UDP
encapulated traffic, we need to reflect that through the hw_enc_features
field of the bonding net-device. This will cause the xmit path
in the core networking stack to provide bonding with encapsulated
GSO frames to offload into the HW etc.

To make TLB mode work, the patch allows learning packets
to be sent using mac addresses assigned to macvlan devices,
also taking into an account vlans that may be between the
bond and macvlan device.
To make RLB work, all we have to do is accept ARP packets
for addresses added to the bond dev->uc list. Since RLB
mode will take care to update the peers directly with
correct mac addresses, learning packets for these addresses
do not have be send to switch.

Bonding devices manage the unicast filters of the underlying
interfaces, but do not turn on IFF_UNICAST_FLT flag. Thus
anytime a unicast address is added to the bond, the bond is
places in promiscuous mode.
Turn on IFF_UNICAST_FLT on the bond device so that the bond does
not go into promiscuous mode needlesly. If an underlying device
does not support unicast filtering, that device will automaticall
enter promiscuous mode already.

ALB learning packets are currentlyalways sent using the slave mac
address for all vlans configured on top of bond. This is not always
correct, as vlans may change their mac address.
This patch introduced a concept of strict matching where the
source of learning packets can either strictly match the address
passed in, or it can determine a more correct address to use.
There are 3 casese to consider:
1) Switchover. In this case, we have a new active slave and we need
tell the switch about all addresses available on the slave.
2) Monitor. We'll periodically refresh learning info for all slaves.
In this case, we refresh all addresses for current active, and just
the slave address for other slaves.
3) Teaching of disabled adddress. This happens as part of the
failover and in this case, we alwyas to use just the address
provided.

The new bond_free_slave() needs new_slave->bond to verify if additional
structures were allocated, so populate it early so that, in case of failure
in bond_enslave(), we would be able to get it.
Also populate the new_slave->dev field, as it's too one of the most needed

that is no longer the case since we now have support for Q-in-Q

bond_compute_features() uses netdev_increment_features() to
combine vlan_features of slaves into vlan_features of the bond.
As netdev_increment_features() only adds most features and we
start with BOND_VLAN_FEATURES, we can end up with features none
of the slaves provided.
If there is at least one slave, initialize vlan_features only
with the flags in NETIF_F_ALL_FOR_ALL. Right now there is none
in BOND_VLAN_FEATURES but stating it explicitely will make the
code more future proof.

Prior to commit fbd929f2dce460456807a51e18d623db3db9f077
bonding: support QinQ for bond arp interval
the arp monitoring code allowed for proper detection of devices
stacked on top of vlans. Since the above commit, the
code can still detect a device stacked on top of single
vlan, but not a device stacked on top of Q-in-Q configuration.
The search will only set the inner vlan tag if the route
device is the vlan device. However, this is not always the
case, as it is possible to extend the stacked configuration.
With this patch it is possible to provision devices on
top Q-in-Q vlan configuration that should be used as
a source of ARP monitoring information.
For example:
ip link add link bond0 vlan10 type vlan proto 802.1q id 10
ip link add link vlan10 vlan100 type vlan proto 802.1q id 100
ip link add link vlan100 type macvlan
Note: This patch limites the number of stacked VLANs to 2,
just like before. The original, however had another issue
in that if we had more then 2 levels of VLANs, we would end
up generating incorrectly tagged traffic. This is no longer
possible.

The aggresive load balancing causes packet re-ordering as active
flows are moved from a slave to another within the group. Sometime
this aggresive lb is not necessary if the preference is for less
re-ordering. This parameter if used with value "0" disables
this dynamic flow shuffling minimizing packet re-ordering. Of course
the side effect is that it has to live with the static load balancing
that the hashing distribution provides. This impact is less severe if
the correct xmit-hashing-policy is used for the tlb setup.
The default value of the parameter is set to "1" mimicing the earlier
behavior.
Ran the netperf test with 200 stream for 1 min between two hosts with
4x1G trunk (xmit-lb mode with xmit-policy L3+4) before and after these
changes. Following was the command used for those 200 instances -
netperf -t TCP_RR -l 60 -s 5 -H <host> -- -r81920,81920

Re-organized the xmit function for the lb mode separating tlb xmit
from the alb mode. This will enable use of the hashing policies
like 802.3ad mode. Also extended use of xmit-hash-policy to tlb mode.
Now the tlb-mode defaults to BOND_XMIT_POLICY_LAYER2 if the xmit policy
module parameter is not set (just like 802.3ad, or Xor mode).

bond_open is not setting the inactive flag correctly for some modes (alb and
tlb), resulting in error behavior if the bond has been administratively set
down and then back up. This effect should not occur when slaves are added while
the bond is up; it's something that only happens after a down/up bounce of the
bond.
For example, in bond tlb or alb mode, domu send some ARP request which go out
from dom0 bond's active slave, then the ARP broadcast request packets go back to
inactive slave from switch, because the inactive slave's inactive flag is zero,
kernel will receive the packets and pass them to bridge that cause dom0's bridge
map domu's MAC address to port of bond, bridge should map domu's MAC to port of
vif.

This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL)
The rcu_assign_pointer() ensures that the initialization of a structure
is carried out before storing a pointer to that structure.
And in the case of the NULL pointer, there is no structure to initialize.
So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL)

The bond send arp request to indicate that the slave is active, and if the bond dev
is a vlan dev, it will set the vlan tag in skb to notice the vlan group, but the
bond could only send a skb with 802.1q proto, not support for QinQ.
So add outer tag for lower vlan tag and inner tag for upper vlan tag to support QinQ,
The new skb will be consist of two vlan tag just like this:
dst mac | src mac | outer vlan tag | inner vlan tag | data | .....
If We don't need QinQ, the inner vlan tag could be set to 0 and use outer vlan tag
as a normal vlan group.

We didn't correctly check cases where the value for lp_interval is not
within the legal range due to a missing table terminator.
This would let userspace trigger a kernel panic by specifying a value out
of range:
echo -1 > /sys/devices/virtual/net/bond0/bonding/lp_interval
Introduced by commit 4325b374f84 ("bonding: convert lp_interval to use
the new option API").
