From 4ab372d49a6e82b0bf097dedb96d26330c5f2d5f Mon Sep 17 00:00:00 2001 From: Szabolcs Nagy Date: Sun, 24 Apr 2016 17:39:02 +0200 Subject: [PATCH] ip: fix problem on mips64 n64 big endian musl systems Use designated initializers for struct msghdr. The struct layout is non-portable and musl libc does not match what busybox expects.
