* Add support for a multipoint-to-multipoint mode in vxlan(4). In thisreyk2016-09-031-3/+5
| | | | | | | | | | | | mode, vxlan(4) must be configured to accept any virtual network identifier with "vnetid any" and added to a bridge(4) or switch(4). This way the driver will dynamically learn the tunnel endpoints and their vnetids for the responses and can be used to dynamically bridge between VXLANs. It is also being used in combination with switch(4) and the OpenFlow tunnel classifiers. With input from yasuoka@ goda@ OK deraadt@ dlg@
* Define VXLAN_VNI_UNSET and VXLAN_VNI_MAX instead of using magic numbers.reyk2016-08-071-1/+4

* Keep "struct vxlan_softc" private to prevent pulling more headers whenmpi2015-11-271-20/+1

* tweak the vnetid so it can be optional and therefore cleared/deleted.dlg2015-10-231-2/+2
| | | | | | | | | | | | | | the abstract vnetid is promoted to a uin32_t, and adds a SIOCDVNETID ioctl so it can be cleared. this is all because i set an assignment on implementing a virtual network interface and the students got confused when vnetid 0 didnt show up in ifconfig output. the vnetid in the vxlan(4) protocol is optional, but the current code confuses 0 with no vnetid being set. this makes it clear. ok reyk@ who also simplified my diff

interface. VXLAN is a UDP-based tunnelling protocol for overlaying virtualized layer 2 networks over layer 3 networks. The implementation is based on draft-mahalingam-dutt-dcops-vxlan-04 and has been tested with other implementations in the wild. put it in deraadt@
