This patch allows to switch the netns when packet is encapsulated or
decapsulated.
The vxlan socket is openned into the i/o netns, ie into the netns where
encapsulated packets are received. The socket lookup is done into this netns to
find the corresponding vxlan tunnel. After decapsulation, the packet is
injecting into the corresponding interface which may stand to another netns.

When one of the two netns is removed, the tunnel is destroyed.

Configuration example:
ip netns add netns1
ip netns exec netns1 ip link set lo up
ip link add vxlan10 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0
ip link set vxlan10 netns netns1
ip netns exec netns1 ip addr add 192.168.0.249/24 broadcast 192.168.0.255 dev vxlan10
ip netns exec netns1 ip link set vxlan10 up

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).

Modified the hash function to return just hash separating from the

make way for the tlb mode to use the same hashing policies that
are used in the 802.3ad and Xor mode.

Intel Wired LAN Driver Updates

This series contains updates to ixgbe, ixgbevf, e1000e, igb and i40e.

Jacob converts the ixgbe low_water into an array which allows the
algorithm to output different values for different TCs and we can
distinguish between them.  Removes vlan_filter_disable() and
vlan_filter_enable() in ixgbe so that we can do the work directly in
set_rx_mode().  Changes the setting of multicast filters only when
the interface is not in promiscuous mode for multicast packets in
ixgbe.  Improves MAC filter handling by adding mac_table API based
on work done for igb, which includes functions to add/delete MAC
filters.

Mark changes register reads in ixgbe to an out-of-line function since
register reads are slow.

Emil provides a ixgbevf patch to update the driver description since
it supports more than just 82599 parts now.

David provides several cleanup patches for e1000e which resolve some
checkpatch issues as well as changing occurrences of returning 0 or 1 in
bool functions to returning true false or true.

Carolyn provides several cleanup patches for igb which fix checkpatch
warnings.

Mitch provides a fix for i40evf where the driver would correctly allow
the virtual function link state to be controlled by 'ip set link', but
would not report it correctly back.  This is fixed by filling out
the appropriate field in the VF info struct.

net: via-rhine: add support for on-chip Rhine controllers

This series introduces platform bus (OpenFirmware) binding for
via-rhine, as used in various ARM-based Systems-on-Chip by
VIA/WonderMedia.

This has been tested in OF configuration by myself on a WM8950-based VIA
APC Rock development board and on a WM8850-based netbook, and in PCI
configuration by Roger.

Please note that the initial version of these patches was signed off by
Roger, but some time has passed since then, so I'm not including his
sign-off until explicit notice.

Changes since v1:
 - Fixed indentation of function arguments
 - Switched to 'dev_is_pci' instead of string comparison on bus name
 - Dropped 'rhine,revision' DT attribute, put the revision into OF match
        table instead
 - Included actual device tree nodes where applicable

entry with several remotes, the deleted remote was not advertised.

In ksz9021_load_values_from_of() val2 to val4 aren't tested against their
initialization value.
This causes the test to always succeed, and this value to be used as if it
was loaded from the devicetree instead of being ignored, in case of a
missing/invalid property in the ethernet OF device node.
As a result, the value "0" is written to the relevant registers.

the locking overhead is reduced especially when multiple channels
are in use.

The recv_pkt_list isn't actually necessary because the packets are
processed sequentially in each channel. It has been replaced by a
local variable, and the related lock for this list is also removed.
The is_data_pkt field is not used in receive path, so its assignment
