            Bug ID: 213618
           Summary: When running as a Hyper-V Guest, FreeBSD 11 networking
                    does not work
           Product: Base System
           Version: 11.0-RC1
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: caesar@starkreality.com
                CC: freebsd-amd64@FreeBSD.org

Host OS: Windows Server 2012
Guest OS: FreeBSD 11.0-RELEASE-p1

Neither the syntetic hnX NIC or the emulated Tulip deX NICs appear to be ab=
le
to transmit.  The NICs are detected, and appear to be able to receive traff=
ic
(IPv6 SLAAC works, tcpdump shows broadcast/multicast traffic), but the NICs=
 are
unable to transmit.  dhclient complains send_packet: No buffer space availa=
ble.
 After configuring a static address with ifconfig, attempts to send packets=
 via
ping do not show up in a tcpdump.  This has been verified under the followi=
ng
conditions:

10.3-RELEASE upgrade to 11.0-RELEASE
11.0-RELEASE fresh installation from .iso
11.0-RELEASE .vhd image from ftp.freebsd.org
