[ Upstream commit 303c07db487be59ae9fda10600ea65ca11c21497 ]

If a qdisc is installed on a ppp device, its possible to get
a lockdep splat under stress, because nested dev_queue_xmit() can
lock busylock a second time (on a different device, so its a false
positive)

Avoid this problem using a distinct lock_class_key for ppp
devices.

pptp always use init_net as the net namespace to lookup
route, this will cause route lookup failed in container.

because we already set the correct net namespace to struct
sock in pptp_create,so fix this by using sock_net(sk) to
replace &init_net.

Add 64 bit stats to ppp driver.  The 64 bit stats include tx_bytes,
rx_bytes, tx_packets and rx_packets.  Other stats are still 32 bit.
The 64 bit stats can be retrieved via the ndo_get_stats operation.  The
SIOCGPPPSTATS ioctl is still 32 bit stats only.
