Part of this patch was merged in upstream, so we need to drop it here.

torrents. Thread on turris forum:

Take Wi-Fi drivers from 23.05 as we are using 5.15 anyway and those are
more suited for it.

If firewall ver. 3 is installed, then iptables switched to legacy mode. With
this option we keep compatibility with other packages like mwan3 which reguires
iptables in legacy mode. When switche to firewall ver. 4, iptables is switched
back to nft mode.

In new lxc version old settings for network were not applied.
Modified current patch for applying right network parameters.
