From 796e549822bdb49128578d8ae82d28a5249b4816 Mon Sep 17 00:00:00 2001 From: Sean Edmond Date: Fri, 6 Jan 2023 14:22:55 -0800 Subject: net: ipv6: Fix IPv6 netmask parsing It should be possible to specify a netmask when setting a static IPv6 address. For example: setenv ip6addr 2001:cafe:cafe:cafe::100/64 The net_prefix_length and net_ip6 should be updated properly.
