veth: extend features to support tunneling
While investigating on a recent vxlan regression, I found veth
was using a zero features set for vxlan tunnels.
We have to segment GSO frames, copy the payload, and do the checksum.
This patch brings a ~200% performance increase
We probably have to add hw_enc_features support
on other virtual devices.

inet: restore gso for vxlan
Alexei reported a performance regression on vxlan, caused
by commit
3347c9602955 "ipv4: gso: make inet_gso_segment() stackable"
GSO vxlan packets were not properly segmented, adding IP fragments
while they were not expected.
Rename 'bool tunnel' to 'bool encap', and add a new boolean
to express the fact that UDP should be fragmented.
This fragmentation is triggered by skb->encapsulation being set.
Remove a "skb->encapsulation = 1" added in above commit,
as its not needed, as frags inherit skb->frag from original
GSO skb.

bonding: patchset for rcu use in bonding
The slave list will add and del by bond_master_upper_dev_link() and

even it is safe to call it in write bond lock now, but we can't sure
that whether it is safe later, because other drivers may deal
NETDEV_CHANGEUPPER in sleep way, so I didn't admit move the
bond_upper_dev_unlink() in write bond lock.
now the bond_for_each_slave only protect by rtnl_lock(), maybe use
bond_for_each_slave_rcu is a good way to protect slave list for bond,
but as a system slow path, it is no need to transform
bond_for_each_slave() to bond_for_each_slave_rcu() in slow path, so in
the patchset, I will remove the unused read bond lock for monitor

2. A follow up issue, pci_enable_sriov() should only be called if no VFs were
still allocated on module unload. Otherwise pci_enable_sriov() gets called
multiple times in a row rendering the NIC unusable until reset.
3. simply calling igb_enable_sriov() in igb_probe_vfs() is not enough as the
interrupts need to be re-setup. Switching that to igb_pci_enable_sriov().

Merge tag 'batman-adv-for-davem' of git://git.open-mesh.org/linux-merge
Antonio Quartulli says:
====================
this is another set of changes intended for net-next/linux-3.13.
(probably our last pull request for this cycle)
Patches 1 and 2 reshape two of our main data structures in a way that they can
easily be extended in the future to accommodate new routing protocols.
Patches from 3 to 9 improve our routing protocol API and its users so that all
the protocol-related code is not mixed up with the other components anymore.
Patch 10 limits the local Translation Table maximum size to a value such that it
can be fully transfered over the air if needed. This value depends on
fragmentation being enabled or not and on the mtu values.
Patch 11 makes batman-adv send a uevent in case of soft-interface destruction
while a "bat-Gateway" was configured (this informs userspace about the GW not
being available anymore).
Patches 13 and 14 enable the TT component to detect non-mesh client flag
changes at runtime (till now those flags where set upon client detection and
were not changed anymore).
Patch 16 is a generalisation of our user-to-kernel space communication (and
viceversa) used to exchange ICMP packets to send/received to/from the mesh
network. Now it can easily accommodate new ICMP packet types without breaking
the existing userspace API anymore.
Remaining patches are minor changes and cleanups.

batman-adv: include the sync-flags when compute the global/local table CRC
Flags covered by TT_SYNC_MASK are kept in sync among the
nodes in the network and therefore they have to be
considered while computing the global/local table CRC.
In this way a generic originator is able to understand if
its table contains the correct flags or not.
Bits from 4 to 7 in the TT flags fields are now reserved for
"synchronized" flags only.
This allows future developers to add more flags of this type
without breaking compatibility.

macvlan: resolve ENOENT errors on creation
After the commit below attempting to create macvlan devices was
resulting in ENOENT errors,
# ip link add link p3p2 type macvlan
RTNETLINK answers: Invalid argument
This happens because netdev_upper_dev_link() is called before
register_netdevice() in the macvlan code. Through a call chain
this results in a call to __netdev_adjacent_dev_insert() and
finally a sysfs_create_link(). This requires the kobject of
the macvlan to be registered which is done in register_netdevice().
If there is no kobject which is the case here the ENOENT error
is seen on the command line.
To resolve this move the netdev_upper_dev_link() call below
the register_netdevice() call. This aligns with vlan driver
flow.
Regression introduced here,

bonding: move bond-specific init after enslave happens
As Jiri noted, currently we first do all bonding-specific initialization
(specifically - bond_select_active_slave(bond)) before we actually attach
the slave (so that it becomes visible through bond_for_each_slave() and
friends). This might result in bond_select_active_slave() not seeing the
first/new slave and, thus, not actually selecting an active slave.
Fix this by moving all the bond-related init part after we've actually
completely initialized and linked (via bond_master_upper_dev_link()) the
new slave.
Also, remove the bond_(de/a)ttach_slave(), it's useless to have functions
to ++/-- one int.
After this we have all the initialization of the new slave *before*
linking, and all the stuff that needs to be done on bonding *after* it. It
has also a bonus effect - we can remove the locking on the new slave init
completely, and only use it for bond_select_active_slave().

====================
Intel Wired LAN Driver Updates
This series contains updates to i40e only.
Jesse provides 6 patches against i40e. First is a patch to reduce
CPU utilization by reducing read-flush to read in the hot path. Next
couple of patches resolve coverity issues reported by Hannes Frederic
Sowa <hannes@stressinduktion.org>. Then Jesse refactored i40e to cleanup
functions which used cpu_to_xxx(foo) which caused a lot of line wrapping.
Mitch provides 2 i40e patches. First fixes a panic when tx_rings[0]
are not allocated, his second patch corrects a math error when
assigning MSI-X vectors to VFs. The vectors-per-vf value reported
by the hardware already conveniently reports one less than the actual
value.
Shannon provides 5 patches against i40e. His first patch corrects a
number of little bugs in the error handling of irq setup, most of
which ended up panicing the kernel. Next he fixes the overactive
IRQ issue seen in testing and allows the use of the legacy interrupt.
Shannon then provides a cleanup of the arguments declared at the
beginning of each function. Then he provides a patch to make sure
that there are really rings and queues before trying to dump
information in them. Lastly he simplifies the code by using an
already existing variable.
Catherine provides an i40e patch to bump the version.

Revert "bridge: only expire the mdb entry when query is received"
While this commit was a good attempt to fix issues occuring when no
multicast querier is present, this commit still has two more issues:
1) There are cases where mdb entries do not expire even if there is a
querier present. The bridge will unnecessarily continue flooding
multicast packets on the according ports.
2) Never removing an mdb entry could be exploited for a Denial of
Service by an attacker on the local link, slowly, but steadily eating up
all memory.
Actually, this commit became obsolete with
"bridge: disable snooping if there is no querier" (
b00589af3b)
which included fixes for a few more cases.

s390/time: correct use of store clock fast
The result of the store-clock-fast (STCKF) instruction is a bit fuzzy.
It can happen that the value stored on one CPU is smaller than the value
stored on another CPU, although the order of the stores is the other
way around. This can cause deltas of get_tod_clock() values to become
negative when they should not be.
We need to be more careful with store-clock-fast, this patch partially
reverts git commit
e4b7b4238e666682555461fa52eecd74652f36bb "time:
always use stckf instead of stck if available". The get_tod_clock()
function now uses the store-clock-extended (STCKE) instruction.
get_tod_clock_fast() can be used if the fuzziness of store-clock-fast
is acceptable e.g. for wait loops local to a CPU.
