[PATCH 1/2] realtek: Use firewall4

[Petr Štetiar]

Hauke Mehrtens <hauke at hauke-m.de> [2022-02-28 22:37:29]:

> The realtek target is not a router, but basic device, see DEVICE_TYPE.
> The basic device type does not come with firewall by default, see
> include/target.mk for details. The realtek target extended
> DEFAULT_PACKAGES manually with firewall.
> 
> This changes the defaults to take firewall4 and nftables instead of
> firewall and iptables. This also adds the additional package
> kmod-nft-offload.
> The only difference to the router type is the missing ppp and
> ppp-mod-pppoe package.
> 
> This increases the compressed image size by about 260KBytes.
