Re: pppx(4): kill pppx_ifs_lk

I missed explanation. All the code protected by this rwlock is KERNEL_LOCK()’ed. The context switches which can be caused by memory allocation or NET_LOCK() dances within pppx_add_session() and pppx_if_destroy() are not under acquired pppx_if_lk. So there is no concurrent access to structures

pppx(4): kill pppx_ifs_lk
