From f3de6f4eccddfcaf3f8b3674ab57a0646b572650 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 27 Apr 2022 23:05:34 -0400 Subject: net: 6lowpan: constify lowpan_nhc structures This patch constify the lowpan_nhc declarations. Since we drop the rb node datastructure there is no need for runtime manipulation of this structure.
