Subject: [PATCH] Avoid in6_addr redefinition

Due to both <netinet/in.h> and <linux/in6.h> being included, the
in6_addr is being redefined: once from the C library headers and once
from the kernel headers. This causes some build failures with for
example the musl C library.

In order to fix this, use just the C library header <netinet/in.h>.
Original patch taken from
http://git.alpinelinux.org/cgit/aports/tree/main/iproute2/musl-fixes.patch.

(Refreshed the patch for 4.6 release)
