Gao Feng e5dadc65f9 ppp: Fix false xmit recursion detect with two ppp devices ... The global percpu variable ppp_xmit_recursion is used to detect the ppp xmit recursion to avoid the deadlock, which is caused by one CPU tries to lock the xmit lock twice. But it would report false recursion when one CPU wants to send the skb from two different PPP devices, like one L2TP on the PPPoE. It is a normal case actually. Now use one percpu member of struct ppp instead of the gloable variable to detect the xmit recursion of one ppp device.
