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.

Fdb usage message got too long.

Add the vlan command documentation to bridge man page.
Signed-off-by: Vlad Yasevich <vyasevic@redhat.com>

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.

Not all arch have sizeof(unsigned long long) == sizeof(__u64)

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).

Add casts to handle printf format when
 sizeof(unsigned long long) != sizeof(__u64)
