I have allocated
  #define DLT_VSOCK               271


    Stefan> Hi, Gerard Garcia previously requested a linktype for AF_VSOCK in
    Stefan> July 2016 (http://seclists.org/tcpdump/2016/q3/17).  I am picking
    Stefan> up his work now that the vsockmon Linux kernel module has been
    Stefan> merged upstream.  The header files and struct definitions are
    Stefan> available as part of the Linux kernel headers.

    Stefan> AF_VSOCK is a guest<->host communications mechanism available in
    Stefan> VMware and KVM hypervisors.  It is not based on Ethernet or IP
    Stefan> but offers SOCK_STREAM and SOCK_DGRAM (only on VMware) semantics
    Stefan> analogous to TCP and UDP.

    Stefan> The vsockmon packet capture headers are here:

    Stefan>   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/vsockmon.h

    Stefan> The virtio-vsock transport headers are here:

    Stefan>   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/virtio_vsock.h

    Stefan> For your convenience I have included a full header description
    Stefan> below based on a draft previously posted by Guy Harris.

    Stefan> You can find more information about virtio-vsock and how to try
    Stefan> it out at http://qemu-project.org/Features/VirtioVsock.

    Stefan> Please assign a linktype for AF_VSOCK.

    Stefan> Thanks, Stefan
