Subject: networkd-ipv4acd.c: Use net/if.h for getting IFF_LOOPBACK definition
X-Git-Tag: v253-rc1~573
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=239e4a42a69c31e55e58618d800e0d68c68931d3;p=thirdparty%2Fsystemd.git

networkd-ipv4acd.c: Use net/if.h for getting IFF_LOOPBACK definition

This helps in avoiding compiling errors on musl. Definition of
IFF_LOOPBACK is the reason for including linux/if_arp.h, this however
could be obtained from net/if.h glibc header equally and makes it
portable as well.
