From 842841ece540f7d7739bec3e9b79bdf9669d77d7 Mon Sep 17 00:00:00 2001 From: Dave Taht Date: Mon, 2 Sep 2019 16:29:36 -0700 Subject: [PATCH] Convert usage of IN_MULTICAST to ipv4_is_multicast MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit IN_MULTICAST's primary intent is as a uapi macro. Elsewhere in the kernel we use ipv4_is_multicast consistently. This patch unifies linux's multicast checks to use that function rather than this macro.
