Subject: pppoe: drop PPPOX_ZOMBIEs in pppoe_release
From: Xiaodong Xu <[email protected]>
[ Upstream commit 2b018d57ff18e5405823e5cb59651a5b4d946d7b ]
When PPPOE is running over a virtual ethernet interface (e.g., a
bonding interface) and the user tries to delete the interface in case
the PPPOE state is ZOMBIE, the kernel will loop forever while
unregistering net_device for the reference count is not decreased to
zero which should have been done with dev_put().
