24 | * NOTE TO MAINTAINERS: | |
25 | * If you modify this file at all, please set the above date. | |
26 | * if_ppp.h is shipped with a PPP distribution as well as with the kernel; | |
27 | * if everyone increases the FILEVERSION number above, then scripts | |
28 | * can do the right thing when deciding whether to install a new if_ppp.h | |
29 | * file. Don't change the format of that line otherwise, so the | |
30 | * installation script can recognize it. | |
