This is an implementation of Virtual eXtensible Local Area Network as described in draft RFC: http://tools.ietf.org/html/draft-mahalingam-dutt-dcops-vxlan-02 The driver integrates a Virtual Tunnel Endpoint (VTEP) functionality that learns MAC to IP address mapping. This implementation has not been tested only against the Linux userspace implementation using TAP, not against other vendor's equipment.

The only change is:

IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
|
|
more not changeable by user. They describe link media
|
|
characteristics and set by device driver.
|

Comments:
|
|
- Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
|
|
- If neither of these three flags are set;
|
|
the interface is NBMA.
|
|
|
|
- IFF_MULTICAST does not mean anything special:
|
|
multicasts can be used on all not-NBMA links.
|
|
IFF_MULTICAST means that this media uses special encapsulation
|
|
for multicast frames. Apparently, all IFF_POINTOPOINT and
|
|
IFF_BROADCAST devices are able to use multicasts too.
