When dumping L2TP PPP sessions using /proc/net/l2tp, get the assigned PPP device name from PPP using ppp_dev_name(). Signed-off-by: James Chapman <jchapman@katalix.com> Reviewed-by: Randy Dunlap <redacted>Why is this a necessary API? Why not put it in debugfs if just a debugging tool?
With the original driver (merged in 2.6.23), some people use horrible hacks in scripts to derive info about their L2TP connections from /proc. So I was reluctant to move it to debugfs in the new driver. If it is ok to move an existing /proc file to debugfs, I'm happy to do so. People should obtain such info from their L2TP userspace daemon, or through netlink anyway. -- James Chapman Katalix Systems Ltd http://www.katalix.com Catalysts for your Embedded Linux software development
