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.

m_ipt.c:361: error: no previous prototype for 'build_st'
make[1]: *** [m_ipt.o] Error 1
This is fixed by adding the prototype in the header include/iptables.h
I am not sure if this is due to something wrong on my build system but I am
using current glibc 2.17.

This patch allows to manage ip6 tunnels via the interface ip link.
The syntax for parameters is the same that 'ip -6 tunnel'.
It also allows to display tunnels parameters with 'ip -details link' or
'ip -details monitor link'.

Minor cleanup of original patch, made sure netconf.h matched
result of santized kernel headers

We support get/del for single entry and dump for

Both macros are used together, so better to have
single define. Update all requests in ipl2tp.c to use the
new macro.

Create libgenl.h and libgenl.c. They will contain
common code for GENL users such as ipl2tp, tcp_metrics, etc.

Both rtnl_talk and rtnl_dump had a callback for handling portions
of netlink message that do not match the correct pid or seq.
But this callback was never used by any part of iproute2 so remove
it.
