[PATCH 0/7] netfilter: kconfig symbol updates

[Yousong Zhou]

The series was based work by Tony Ambardar in GitHub pull request [1].
Many investigations were done by Tony. And many changes were done by me
and all errors are mine of course.

 [1] https://github.com/openwrt/openwrt/pull/3257

The work foucused on the following aspects.

 - Use current config symbols when possible, instead of those retained
   for compat reasons
 - Many kconfig symbols for conntrack and nat functions are now bool
   with prompt ones, instead of the old tristate ones.  Version
   conditionals are added for old kernel versions.  And make them unset
   state as these options can only be enabled when selected by others

Tony Ambardar (1):
  netfilter.mk: add version conditional for CONFIG_NF_CT_PROTO_GRE
