            Bug ID: 196744
           Summary: Hyper-V synthetic network driver ipv6 dad
           Product: Base System
           Version: 10.1-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: steve.bauer@sdsmt.edu

When configuring the virtual machine to use VMQ, the ipv6 support in the guest
is disabled because it detects a duplicate ipv6 address on both the statically
assigned address as well as the link-local address.

The workaround for this issue is to disable VMQ for the virtual machine.

Host Machine:  ibm 3650 M4 with intel x520 10Gbps dual port adapter with
windows server 2012 R2 patched with the updates through January 2015

Guest machine:  FreeBSD 10.1 stable release 277209
