Subject: netfilter.mk: add version conditional around nf_nat_redirect mod
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=dd5b04bf986962d449d0c7943c712f50aa60bfcc;p=openwrt%2Fstaging%2Fthess.git

netfilter.mk: add version conditional around nf_nat_redirect mod

Kernel commit 1ac89d20150e ("netfilter: nat: merge nf_nat_redirect into
nf_nat") made the redirect module part of the nat core and changed the
CONFIG_NF_NAT_REDIRECT option to a boolean, without prompt, affecting
kernel 4.18 onwards.  CONFIG_NF_NAT_REDIRECT now can only be selected by
CONFIG_NFT_REDIR or NETFILTER_XT_TARGET_REDIRECT

Fixes: FS#2476

Fixes: FS#2990 (partial)
Ref: https://bugs.openwrt.org/index.php?do=details&task_id=2990

[note that the option has no prompt and can only be selected by other
kconfig options]
