The newly added NF_FLOW_TABLE options cause some build failures in
randconfig kernels:
- when CONFIG_NF_CONNTRACK is disabled, or is a loadable module but
NF_FLOW_TABLE is built-in:
In file included from net/netfilter/nf_flow_table.c:8:0:

- when CONFIG_NF_FLOW_TABLE_INET is enabled, but NF_FLOW_TABLE_IPV4
or NF_FLOW_TABLE_IPV6 are not, or are loadable modules
net/netfilter/nf_flow_table_inet.o: In function `nf_flow_offload_inet_hook':

- when CONFIG_NF_FLOW_TABLES is disabled, but the other options are
enabled:

nf_flow_table_inet.c:(.text+0x6c): undefined reference to `nf_flow_offload_ipv6_hook'

This adds additional Kconfig dependencies to ensure that NF_CONNTRACK and NF_TABLES
are always visible from NF_FLOW_TABLE, and that the internal dependencies between
the four new modules are met.

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.
