Patch

[Comment 2 G.Wolfe Woodbury 2012-07-26 13:44:12 UTC]

I am seeing this also

The previous patch is merely making the package pppol2tp.h file
the same as the kernel-headers-3.5 version.

better solution is to simply use

#include <linux/if_pppol2tp.h>

Hm - where…?

[Comment 4 Chin Jin Phua 2012-07-27 13:51:39 UTC]

if_ppp.h? Why is there a need to include your own linux headers?
