The workaround is to disable UPD checksum offloading in the FreeBSD guest through 'ifconfig'. We are also working on a patch to turn off UPD checksum offloading in the netvsc driver when detecting the Hyper-V releases. The UDP checksum offloading works fine on Windows Server 2012R2 and Win 8.1 hosts. Thanks Pavel and Slawa for the support.
