Subject: [PATCH] econet: have failed ec_queue_packet() call return
 NET_RX_BAD

econet_rcv() calls ec_queue_packet(). The return from ec_queue_packet()
is the direct result of a call to sock_queue_rcv_skb(). Error returns
from ec_queue_packet() and therefore sock_queue_rcv_skb() are due to
kernel errors, so have econet_rcv() return NET_RX_BAD in this case.

If my understanding is correct, then
