This patch add support of netlink messages for AF_PACKET and thus it allows
to get filter information of this kind of sockets.
To dump these filters info the option --bfp must be specified and the user
must have admin rights.

This is now possible, because the dump function has been added in kernel.
Note that IPv4 and IPv6 entries are displayed.

Before this patch, only all entries were displayed.

Example:
$ ip netconf
ipv4 dev lo forwarding on rp_filter off mc_forwarding 0
ipv4 dev eth0 forwarding on rp_filter off mc_forwarding 1
ipv4 all forwarding on rp_filter off mc_forwarding 1
ipv4 default forwarding on rp_filter off mc_forwarding 0
ipv6 dev lo forwarding on mc_forwarding 0
ipv6 dev eth0 forwarding on mc_forwarding 0
ipv6 all forwarding on mc_forwarding 0
ipv6 default forwarding on mc_forwarding 0

For later ss change.

This change shifts burden onto the users to choose the UDP port value.
Kernel default value is incorrect UDP port 5287 but now there is
an official assigned port for VXLAN.

The kernel can't change because of legacy compatibility
but new deployments should not use the legacy port value.

This patch allows setting the "NTF_ROUTER" flag in VXLAN forwarding table
entries to enable L3 switching for router destinations while still allowing
L2 redirection appliances for non-router MAC destinations.

iproute2 patch to generalize VXLAN forwarding tables

This is the iproute2 support allowing an administrator to specify alternate
ports, vnis and outgoing interfaces for VXLAN device forwarding tables.

Changes since v3: changed NDA_PORT to be 16-bit network byte order to match
	changed byte-order/size in the VXLAN driver.

Add ability to set UDP destination port on a per device basis.
If no port is assigned, the default IANA assigned port will be used.
If you want the kernel default value, then use port 0.

Source port range option is now called 'srcport', to avoid
confusion. The old option syntax is accepted for compatiablity.

This patch adds support for tokenized IIDs, that enable
administrators to assign well-known host-part addresses
to nodes whilst still obtaining global network prefix
from Router Advertisements. This is the iproute2 part for
the kernel patch f53adae4eae5 (``net: ipv6: add tokenized
interface identifier support'').

Example commands with iproute2:

Setting a device token:
  # ip token set ::1a:2b:3c:4d/64 dev eth1

Getting a device token:
  # ip token get dev eth1
  token ::1a:2b:3c:4d dev eth1

Listing all tokens:
  # ip token list  (or: ip token)
  token :: dev eth0
  token ::1a:2b:3c:4d dev eth1

Hello!

Subject: [PATCH] Feed GCC 4.8.0 against new warning that is shipped with
 -Wall: -Wsizeof-pointer-memaccess.

In trying to build on a RHEL6.3 I ran into several build issues that are
addressed in this patch.

The first is that xtables_merge_options only has 3 parameters.  It appears
this is how this code was originally.  As such for the case where the version
is less than 6 I am assuming it would be correct to maintain the original
setup that only had 3 parameters being passed instead of 4.

I also ran into an issue with the define for __ALIGN_KERNEL not being present.
I believe this may be due to the fact that __ALIGN_KERNEL was moved into a
separate header from ALIGN after the UAPI changes.  In order to just cover all
of the bases I have moved the main definition for the macros into
__ALIGN_KERNEL_MASK and __ALIGN_KERNEL and if ALIGN is also needed then it is
just a direct redefine to __ALIGN_KERNEL.

Don't call ll_init_map on modify operations
Saves significant overhead with 1000's of devices.

Make ll_ functions faster by having a name hash, and allow
for deletion. Also, allow them to work without calling ll_init_map.

When this flag is set, it means that dump was interrupted and result may be
inconsistent.

Add documentation about the new l2spec_type parameter for "ip l2tp add
session".
Signed-off-by: James Chapman <jchapman@katalix.com>

When unmanaged L2TP sessions are created using "ip l2tp add session",
there is no option to allow the session's Layer2SpecificHeader type to
be selected - the kernel's default setting is always used. For
interopability with some vendor equipment, it might be necessary to
use a different setting. So add a new l2spec_type parameter to the "ip
l2tp add session" parameter list, allowing operators to set a specific
Layer2SpecificHeader type. The kernel already exposes the setting as a
netlink attribute so it is straightforward to add support for it in
iproute2.

This change allows unmanaged L2TP sessions to be configured between
Linux and some Cisco equipment by specifying "l2spec_type none" in "ip
l2tp add session" command parameters.

Better to get prototype from system headers

The address was being stored but not used by current code.

In older versions of traffic shaping the Alpha kernel was special
and had higher HZ. This no longer matters, TC is based on high
resoulution timers in kernel.

My previous commit introduced a patch to allow for states with different
ip address families for selector and id. The must have somehow been a
mixup of the patch I tested and the one I send, so the patch sent breaks
the iproute2 build. This patch fixes this. My apologies.
