Author: sephe Date: Thu Oct 13 06:17:33 2016 New Revision: 307181 URL: https://svnweb.freebsd.org/changeset/base/307181 Log: MFC 304832-304834,304972 304832 hyperv/hn: Use vmbus xact for RNDIS query. And switch MAC address query to use new RNDIS query function. Sponsored by: Microsoft Differential Revision: https://reviews.freebsd.org/D7639 304833 hyperv/hn: Save the adopted NDIS version for RNDIS to use later. Sponsored by: Microsoft Differential Revision: https://reviews.freebsd.org/D7640 304834 hyperv/hn: Use vmbus xact for RNDIS set. And use new RNDIS set to configure NDIS offloading parameters. Sponsored by: Microsoft Differential Revision: https://reviews.freebsd.org/D7641 304972 hyperv/hn: Add definition for NDIS media state.
