These changes are the raw update to linux-4.4.6-rt14. Kernel sources

are taken from kernel.org, and rt patch from the rt wiki download page.

During the rebasing, the following patch collided:

Force tick interrupt and get rid of softirq magic(I70131fb85).

Collisions have been removed because its logic was found on the
source already.

-The VXLAN protocol is a tunnelling protocol that is designed to
-solve the problem of limited number of available VLAN's (4096).
-With VXLAN identifier is expanded to 24 bits.
-
-It is a draft RFC standard, that is implemented by Cisco Nexus,
-Vmware and Brocade. The protocol runs over UDP using a single
-destination port (still not standardized by IANA).
-This document describes the Linux kernel tunnel device,
-there is also an implantation of VXLAN for Openvswitch.
-
-Unlike most tunnels, a VXLAN is a 1 to N network, not just point
-to point. A VXLAN device can either dynamically learn the IP address
-of the other end, in a manner similar to a learning bridge, or the
-forwarding entries can be configured statically.
-
-The management of vxlan is done in a similar fashion to it's
-too closest neighbors GRE and VLAN. Configuring VXLAN requires
-the version of iproute2 that matches the kernel release
-where VXLAN was first merged upstream.
+The VXLAN protocol is a tunnelling protocol designed to solve the
+problem of limited VLAN IDs (4096) in IEEE 802.1q.  With VXLAN the
+size of the identifier is expanded to 24 bits (16777216).
+
+VXLAN is described by IETF RFC 7348, and has been implemented by a
+number of vendors.  The protocol runs over UDP using a single
+destination port.  This document describes the Linux kernel tunnel
+device, there is also a separate implementation of VXLAN for
+Openvswitch.

+either dynamically in a manner similar to a learning bridge, or make

 1. Create vxlan device
-  # ip li add vxlan0 type vxlan id 42 group 239.1.1.1 dev eth1
-
-This creates a new device (vxlan0). The device uses the
-the multicast group 239.1.1.1 over eth1 to handle packets where
-no entry is in the forwarding table.
+ # ip link add vxlan0 type vxlan id 42 group 239.1.1.1 dev eth1 dstport 4789
+
+This creates a new device named vxlan0.  The device uses the multicast
+group 239.1.1.1 over eth1 to handle traffic for which there is no
+entry in the forwarding table.  The destination port number is set to
+the IANA-assigned value of 4789.  The Linux implementation of VXLAN
+pre-dates the IANA's selection of a standard destination port number
+and uses the Linux-selected value by default to maintain backwards
+compatibility.
 
 2. Delete vxlan device
   # ip link delete vxlan0
