[dpdk-dev] [PATCH v8 0/5] Hyper-V netvsc PMD and VMBus support

[Stephen Hemminger]

This is a revised version of the Hyper-V native bus (VMBus)
and network device (netvsc) drivers. 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.

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

v6
  - rebase to current 18.05-rc2
  - fix RSS initialization
  - minor documentation fixes

v5
  - rebase to current 18.05-rc1
  - fix message from vmbus due to race on sysfs for sub channel

v4
  - don't enable by default because of uuid library dependency
  - api's are internal no need to mark experimental
  - add netvsc ini file
  - fix MAINTAINERS entry

v3
  - fix documentation to format correctly and include more info
    about binding
  - fix build on 32 bit
  - minor white space and indentation fixes

Stephen Hemminger (5):
  eal: add rte_uuid support
  bus/vmbus: add hyper-v virtual bus support
  net/netvsc: add hyper-v netvsc network device
  net/netvsc: add documentation
  bus/vmbus and net/netvsc: add meson build support
