From 715c05edd5ed586168faf12d60d7eb10ec0f0dac Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Sat, 3 Dec 2016 17:31:45 +0100 Subject: uapi glibc compat: fix outer guard of net device flags enum [ Upstream commit efc45154828ae4e49c6b46f59882bfef32697d44 ] Fix a wrong condition preventing the higher net device flags IFF_LOWER_UP etc to be defined if net/if.h is included before linux/if.h. The comment makes it clear the intention was to allow partial definition with either parts. This fixes compilation of userspace programs trying to use IFF_LOWER_UP, IFF_DORMANT or IFF_ECHO.
