Add id strings to tun.[ch]. Don't try to open ppp.secret if we're never going to use it. 1997-11-17 01:42:41 +01:00			`*/`

Abstract data read from and written to the tun device, allowing for a possible header on the front of all packets. In OpenBSD, there's a structure containing the address family here. If we're building under OpenBSD, set up the ``flags'' part of struct tuninfo (not there under FreeBSD) so that we config the interface as POINTOPOINT. Prefix prototypes with ``extern'' in os.c for consistency. These changes are cosmetic under FreeBSD, but allow ppp to build & work under OpenBSD (bar the srandomdev() stuff, the inclusing of <net/if_var.h> and some Makefile symantecs). 1997-11-16 23:15:11 +01:00			`struct tun_data {`
Allow a ``timeout secs'' filter option to let specific packet types effect the idle timer in different ways. Submitted by: Stefan Esser <se@freebsd.org> With adjustments by me to document the option in the man page and to give the same semantics for outgoing traffic as incoming. I made the style more consistent in ip.c - this should really have been done as a separate commit. 2000-07-12 00:11:36 +02:00			`union {`
			`u_int32_t family;`

o Move alias function pointers into loadalias.c o Move Var*Version into command.c o Remove struct pppVars (and there was much rejoicing) ! o Forward-decl some structs in .h files to avoid include ordering requirements and remove a few more redundant #includes. 1998-04-07 02:54:26 +02:00			`struct bundle;`

Categorize the fields in struct bundle, and make the tunnel device speed available in ``show bundle''. 1998-05-07 01:50:25 +02:00			`extern void tun_configure(struct bundle *, int);`
