networkd: VXLAN add support to configure port This patch add support to configure port PortRange: VXLAN bases source UDP port based on flow to help the receiver to be able to load balance based on outer header flow. DestinatinPort: Allow configuring the default destination port on a per-device basis.

networkd: vxlan add option to set FDB entries Add support to configures maximum number of FDB entries.

networkd: add bridge properties ForwardDelaySec: forward delay HelloTimeSec: hello time MaxAgeSec: maximum message age for more information see http://www.tldp.org/HOWTO/BRIDGE-STP-HOWTO/set-up-the-bridge.html In kernel br_dev_newlink: does not have the this functionality to set while creation. br_changelink: after creation we can change the parameters. we need to first create then set it the parameters. Introduce new callback post_create .This should set the properties after the creation.

networkd: add support for tunnel encap limit The Tunnel Encapsulation Limit option specifies how many additional levels of encapsulation are permitted to be prepended to the packet

networkd: vxlan add support for GBP This patch add support for vxlan VXLAN Group Policy Option. https://tools.ietf.org/html/draft-smith-vxlan-group-policy-00 http://lwn.net/Articles/628683/

networkd: capitalize VNetHeader= as VnetHeader= Even when we use shortened, combined words, we still should uppercase where a new word starts. I couldn't find a canonically capitalized version of this term, hence I think we should follow our naming rules here.

networkd: add support for macvtap This patch add support for macvtap. see http://virt.kernelnewbies.org/MacVTap

network: rename DiffServiceCodePoint to CopyDSCP Old name was slightly misleading, because this flag does not determine whether DSCP is used overall, but only if it is copied to the decapsulated packet. Rename to better reflect that. "Copy" does not imply direction. This is on purpose, because we might later on enhance the setting to allow/disallow copying in the other direction, to the encapsulated packet. If that is implemented, CopyDSCP could understand additional values. This is nicer than having two separate settings and follows the example of DHCP=. Also, we try to avoid abbreviations, but we allow acronyms like MTU, in DiscoverPathMTU=. This setting was recently added, so it's fine to rename it without backwards compat.

networkd: ip6 tunnel add DSCP This patch adds support for setting the DSCP field in the ip6 tunnel. when set it inherits DSCP field between inner and outer header.

networkd: ip6 tunnel add support for flowlabel Add Pv6 Flow Label support. The 20-bit Flow Label field in the IPv6 header[RFC2460] is used by a node to label packets of a flow.
