hdlc_fr (PVC device) uses dev->priv for N:1 mappings (a single pvc structure may be referenced as dev->priv by multiple (up to 2 currently) PVC devs).

hdlc_ppp obviously has to do some tricks to use syncppp: static int ppp_open(struct net_device *dev) { hdlc_device *hdlc = dev_to_hdlc(dev); void *old_ioctl; int result;
dev->priv = &state(hdlc)->syncppp_ptr; ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ state(hdlc)->syncppp_ptr = &state(hdlc)->pppdev; state(hdlc)->pppdev.dev = dev;
old_ioctl = dev->do_ioctl; state(hdlc)->old_change_mtu = dev->change_mtu; sppp_attach(&state(hdlc)->pppdev);
Perhaps I should remove that and make a sane interface in syncppp. -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
