For older glibc ~2.17, #include'ing both linux/if.h and net/if.h
fails due to complaints about redefinition of interface flags:
CC net.o
In file included from net.c:13:0:
/usr/include/linux/if.h:71:2: error: redeclaration of enumerator ‘IFF_UP’
IFF_UP = 1<<0, /* sysfs */
^
/usr/include/net/if.h:44:5: note: previous definition of ‘IFF_UP’ was here
IFF_UP = 0x1, /* Interface is up. */
The issue was fixed in kernel headers in [1], but since compilation
of net.c picks up system headers the problem can recur.
Dropping #include <linux/if.h> resolves the issue and it is
not needed for compilation anyhow.
