We no longer depend on IPV6, but that now causes a link error with
CONFIG_IPV6=m and CONFIG_IPVLAN=y:
drivers/net/ipvlan/ipvlan_core.o: In function `ipvlan_queue_xmit':
ipvlan_core.c:(.text+0x1440): undefined reference to `ip6_route_output_flags'
drivers/net/ipvlan/ipvlan_core.o: In function `ipvlan_l3_rcv':
ipvlan_core.c:(.text+0x1818): undefined reference to `ip6_route_input_lookup'
This adds back the dependency on IPV6, with the option of building without
IPV6, but forcing IPVLAN to be a module when IPV6 is a module.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
