The vcc_destroy_socket() closes vcc before the protocol is detached from vcc by calling vcc->push() with NULL skb. This leaves some time window, where the protocol may call vcc->send() on closed vcc and crash. Now pppoatm_send(), like vcc_sendmsg(), checks for vcc flags that indicate that vcc is not ready. If the vcc is not ready we just drop frame. Queueing frames is much more complicated because we don't have callbacks that inform us about vcc flags changes.
