Hello Dexuan, I did fresh installation with the current FreeBSD-10.2-RELEASE-amd64-dvd1.iso and this works. Even with the message, as you already mentioned.
With kind regards, Jac -----Oorspronkelijk bericht----- Van: Dexuan Cui [mailto:de...@microsoft.com] Verzonden: dinsdag 26 januari 2016 7:49 Aan: Kylie Liang; Jac Backus; 'freebsd-virtualization@freebsd.org'; BSD Integration Components for Hyper-V Onderwerp: RE: Hyper-V networking: problem after upgrade to 10.2 Hi Jac, Kylie meant disabling TSO. Please try this ("ifconfig hn0 -tso"). The message " hn0: unknown status 1073872902 received" should be an unnecessary warning only. My 10.2 VM can work fine even if I see the message too. Can you please install a 10.2 VM from the 10.2 .ISO file directly as I did and see if it works for you? I guess we never tried upgrading 10.1 from 10.2. Can you please list the steps how you did the upgrading? We'll try the same steps.
