That's odd, but we're not planning to support CentOS/RHEL 7.  CentOS 8 came out recently and we will target that.  I'll 
have a Dockerfile/docker build example image out for that in the not too distant future similar to my Fedora and Ubuntu 
ones.

Yes, /usr/include/linux/netfilter.h exits in my OS(centos7.5/kernel3.10). And I can not found why configure fail.
Adding those checks for linux/types.h and linux/sysctl.h is to resolve the flowing WARING , which suggested by:

I would not suggest doing that.  Which Linux distribution are you using that doesn't have 
/usr/include/linux/netfilter.h?  If it exists but detection fails, check configure.log for why.
Also, why did you add those checks for linux/types.h and linux/sysctl.h?  Was it related to the failure?

I don‘t know if this error is related with that：
When config libdaq， the checking for linux/netfilter.h is always “no”. So I enable the nfq forely as below：
if test "$enable_nfq_module" = yes; then
    AC_CHECK_HEADERS([ linux/types.h])
    AC_CHECK_HEADERS([ linux/sysctl.h])
    AC_CHECK_HEADERS([ linux/netfilter.h linux/netfilter/nfnetlink_queue.h libmnl/libmnl.h], [], 
[enable_nfq_module=yes],   // I change "no" to "yes" to enalbe nfq, because I cant find why  checking for
