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.

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.

Do not enforce the selector of a state to have the same address family
as the id. This makes it possible to configure inter family states.

Recent kernel patches added support for VLAN filtering on the bridge.
This functionality allows one to turn a basic bridge into a VLAN bridge,
where VLANs dicatate packet forwarding and header transformation.
To configure the VLANs on the bridge and its ports a new command is
added to the 'bridge' utility.
# bridge vlan add dev eth0 vid 10 pvid untagged brdev
# bridge vlan add
# bridge vlan delete dev eth0 vid 10
# bridge vlan show
This command supports the following flags:
master - peform the operation on the software bridge device. This is
the default behavior.
self - perform the operation on the hardware associated with the port.
This flag is required when the device is the bridge device and
the configuration is desired on the bridge device itself (not
one of the ports).
pvid - Set the PVID (port vlan id) for a given port. Any untagged
frames arriving on the port will be assigned to this vlan.
untagged - Sets the egress policy of for a given vlan. Default port
egress policy is tagged. Set this flag if you wish traffic
associated with this VLAN to exit the port untagged.

Some platforms like ppc64 have unsigned long long as 128 bits, and
the printf format string would cause errors. Resolve this by using
unsigned long long where necessary (or unsigned long).

This is fixed by adding the prototype in the header include/iptables.h

Clearer error messages for fifo and tbf qdiscs:
- Say who is complaining
- Don't just say a parameter is bad, show the offending parameter
- Be clearer about duplicate parameters vs illegal pairs of parameters
- Try to give multiple error messages rather than let the user discover the errors one by one
- When there are parameter aliases, try to use the variant that was used, or at least mention them all
Note that in the old version an empty parameter list to tbf would just cause an explain() message
without a specific error message. By simply removing the relevant error check, the code now
handles this error more gracefully by printing an error message for all mandatory parameters.
It still prints the explain() message.

Platforms have different alignment requirements which need to be
fulfilled by the compiler. If the structure elements are already
4 byte (NLMGS_ALIGNTO) aligned by the compiler adding an explicit
padding element (align_rta) is not allowed.
Use __attribute__ ((aligned (NLMSG_ALIGNTO))) in order to achieve
the required alignment.
Experienced on ARM (xscale) with symptom

Fixes Debian bug #700434
Need to table id in filter to be unsigned to avoid conversion to -1
The documentation for "ip" suggests that, when using multiple routing tables, the table ID can be an arbitrary 32 bit number. I've been writing a script that calculates a table Id based on an IP addresses and sets up tables accordingly based on it. This seems to work for everything I've tried except "ip route flush". If you specify a table to flush with an ID over 2^31, it flushes all IPv4 routing tables. For example:
Will delete all routing tables, including the default one. Needless to say, this is quite annoying. I think this is an upstream bug, but your opinions will be greatly appreciated.
This patch improves many error messages as follows:
- For incorrect parameters, show the value of the offending parameter, rather than just say that it is incorrect
- Rephrased messages for clarity
- Rephrased to more `mainstream' english
