From 8cdc3223e78c43e1b60ea1c536a103e32fdca3c5 Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Mon, 27 Mar 2023 16:54:54 -0700 Subject: ipv6: Remove in6addr_any alternatives. Some code defines the IPv6 wildcard address as a local variable and use it with memcmp() or ipv6_addr_equal(). Let's use in6addr_any and ipv6_addr_any() instead.
