Hi

Could you add support for nftables nat and postrouting to your kernel builds.

Following situation is

```auto
root@LX2621a:~# zgrep CONFIG_NF_TABLES /proc/config.gz
CONFIG_NF_TABLES=y
# CONFIG_NF_TABLES_INET is not set
# CONFIG_NF_TABLES_NETDEV is not set
CONFIG_NF_TABLES_IPV4=y
# CONFIG_NF_TABLES_ARP is not set
# CONFIG_NF_TABLES_IPV6 is not set
CONFIG_NF_TABLES_BRIDGE=y

```

that what is needed

```auto
zgrep CONFIG_NF_TABLES /proc/config.gz

Ensure the following options are set:

* `CONFIG_NF_TABLES=y`
* `CONFIG_NF_TABLES_INET=y`
* `CONFIG_NF_TABLES_IPV4=y`
* `CONFIG_NF_NAT_IPV4=y`
* `CONFIG_NF_TABLES_IPV6=y`
* `CONFIG_NF_NAT_IPV6=y`

```

How I can build a kernel with this settings and docker?

It’s correct to add following lines

```auto
CONFIG_NF_TABLES_ARP=y
CONFIG_NF_TABLES_IPV6=y
CONFIG_NF_TABLES_INET=y
CONFIG_NF_TABLES_NETDEV=y

```

in

> <https://github.com/SolidRun/lx2160a_build/blob/master/configs/linux/lx2k_additions.config>

will enable full nftables support to the builded image/kernel?

The compiled kernel image works with nftables on this configuration.

We will look into adding this to our next BSP release.
