svn commit: r284889 - head/sys/dev/hyperv/netvsc

[Bjoern A. Zeeb]

Author: bz
Date: Sat Jun 27 12:37:09 2015
New Revision: 284889
URL: https://svnweb.freebsd.org/changeset/base/284889

Log:
  Fix compilation without INET6 and without INET and INET6 after
  offload support was introduced in r284746.
  
  While here also fix the ioctl() handler for IPv4 added in r279819,
  which was never compiled in given opt_inet.h was not included.
