Add new NF* configs to enable more nftables features. Previously 26/300 of the nftables ptests failed, mainly due to 'missing' kernel modules. It's impossible to know which nftables features will be used so add more configs to ensure that most nftables features used by nft work.
The added features are: NF_CONNTRACK_TIMEOUT enables support for connection tracking timeout extension. This allows you to attach timeout policies to flow via the CT target. NF_FLOW_TABLE adds the flow table core infrastructure. NF_FLOW_TABLE_INET adds the flow table mixed IPv4/IPv6 support. NF_FLOW_TABLE_IPV4 adds the flow table IPv4 support. This option goes away in the 5.18 kernel. Without this option 13 rather than 6 nftables tests fail. The NF_FLOW_TABLE_IPV6 config isn't needed but doesn't hurt. NFT_NUMGEN adds the number generator expression used to perform incremental counting and random numbers bound to a upper limit. NFT_OSF allows matching packets from an specific OS. NFT_QUOTA=m adds the "quota" expression that you can use to match enforce bytes quotas. NFT_SYNPROXY=m The SYNPROXY expression allows you to intercept TCP connections and establish them using syncookies before they are passed on to the server. This allows to avoid conntrack and server resource usage during SYN-flood attacks. This brings the nftables-1.0.2 ptest resutls from: [OK] 274 [FAILED] 26 [TOTAL] 300 to: [OK] 294 [FAILED] 6 [TOTAL] 300 The remaining 6 ptests also fail on other distros and with the linux-yocto-dev 5.19.0-rc* kernel. The should/will be fixed eventually.
