From 257aee0cc0306de8bae6b3095908983c3db856d5 Mon Sep 17 00:00:00 2001 From: Shine <4c.fce2@proton.me> Date: Mon, 29 Jun 2026 09:23:45 +0200 Subject: [PATCH] scripts: dhcpv6: don't report custom ip6class if default odhcp6c returns delegated prefixes with a "class=" tag if a custom IAID was specified in the -P argument. This tag must then be used for any prefix filter ("network..ip6class") instead of the uplink i/f name. OpenWrt by default uses the first eight digits of the uplink i/f name's MD5 hash as IAID. Don't report a custom "class" tag for this default IAID.
