This virtual device is used in Microsoft Hyper-V in Windows 10, Windows Server 2016 and Azure. Most of this code was extracted from FreeBSD and some of this is from earlier code donated by Brocade. Only Linux is supported at present, but the code is split to allow future FreeBSD and Windows support. This version works with upstream kernel (4.16) but in that mode only a single queue is supported. With additional patches that are pending for 5.0 kernel, multi-queue support works as well. Device binding is best done via driverctl; this required some additional fixes to kernel and driverctl to work correctly. Linux kernel vmbus support needed to support sysfs driver_override and driverctl needed to handle non-PCI bus from udev. https://gitlab.com/driverctl/driverctl/merge_requests/3 http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2018-April/118889.html v10 - resolve RSS setup - add documentation about restart issue - update documentation to refer to 4.17 - use same RSS key as MLX v9 - fix places where still targeted at previous release - add map entry for rte_uuid - fix meson build dependencies v8 - targeted for 18.08, move release notes - use Ted's libuuid (not FreeBSD) because that is 3 clause BSD license versus 2 clause in FreeBSD - minor checkpatch whitespace fixes v7 - add EAL UUID functions from BSD to remove dependency on libuuid this means device can be enabled by default and eliminates build issues - add support for latest NetVSP protocol (from hayaingz) - add probe finish for compatability with 18.05 - rebase to 18.05-rc3
