> Define PPP device handler for use with rtnetlink. > The only PPP specific attribute is IFLA_PPP_DEV_FD. It is mandatory and > contains the file descriptor of the associated /dev/ppp instance (the > file descriptor which would have been used for ioctl(PPPIOCNEWUNIT) in > the ioctl-based API). The PPP device is removed when this file > descriptor is released (same behaviour as with ioctl based PPP > devices). > > PPP devices created with the rtnetlink API behave like the ones created > with ioctl(PPPIOCNEWUNIT). In particular existing ioctls work the same > way, no matter how the PPP device was created. > The rtnl callbacks are also assigned to ioctl based PPP devices. This > way, rtnl messages have the same effect on any PPP devices. > The immediate effect is that all PPP devices, even ioctl-based > ones, can now be removed with "ip link del". > > A minor difference still exists between ioctl and rtnl based PPP > interfaces: in the device name, the number following the "ppp" prefix > corresponds to the PPP unit number for ioctl based devices, while it is > just an unrelated incrementing index for rtnl ones. > > Signed-off-by: Guillaume Nault <g.na...@alphalink.fr> Series applied, thanks for doing this work!
