[OpenRC / Networking] No buffer space available while IPv6 tunneling.

Heyo,

I got a problem with setting up IPv6 tunnel.
Command ifconfig sit0 inet6 tunnel ::216.66.80.162 has returned an error:
Code: [Select]
SIOCSIFDSTADDR: No buffer space available

Is there any solution to that?

Here's my full script setup:
Code: [Select]
ifconfig sit0 up
ifconfig sit0 mtu 2200
ifconfig sit0 inet6 tunnel ::216.66.80.162
ifconfig sit1 up
ifconfig sit1 mtu 2200
ifconfig sit1 inet6 add 2001:470:70:240::2/64
route -A inet6 add ::/0 dev sit1

Linux kernel version is 6.1.6-artix1-1.

Problem solved.

Those settings must be applied at the system startup before network buffer would be too much fragmented.
