[v5,00/14] add FreeBSD support to VMBUS & NetVSC PMDs

This patchset requires FreeBSD VMBus kernel changes and
HV_UIO driver. Both are currently under review at
https://reviews.freebsd.org/D32184

Changelog:
v5: - renamed dir osi to unix
    - marked a newly added API as experimental
    - removed camel case variables
v4: - moved OS independent code out of Linux
v3: - split the patches into further logical parts
    - updated docs
v2: - replaced strncpy with memcpy
    - replaced malloc.h with stdlib.h
    - added comment in linux/vmbus_uio.c
v1: Intial release

Srikanth Kaka (14):
  bus/vmbus: move independent code from Linux
  bus/vmbus: move independent bus functions
  bus/vmbus: move OS independent UIO functions
  bus/vmbus: scan and get the network device on FreeBSD
  bus/vmbus: handle mapping of device resources
  bus/vmbus: get device resource values using sysctl
  net/netvsc: make event monitor OS dependent
  bus/vmbus: add sub-channel mapping support
  bus/vmbus: open subchannels
  net/netvsc: make IOCTL call to open subchannels
  bus/vmbus: get subchannel info

Is this patch still of interest to anyone?
It is over 3 years old, and would lots of work to rebase on current main branch.
Also, would need ack from existing vmbus maintainers.

Going to close off this version in patchwork as "Changes requested" since it
will need work.
