Details:

Since last changes for TCPIP_MSG_INPKT, there could be a problem with network
interfaces like loopif which enqueue with tcpip_input IP packets, and not
Ethernet packets. The patch fix this problem by checking if the netif got the
NETIF_FLAG_ETHARP flag: in this case, packets are considered like Ethernet
packets, else, they are considered like IP packets. No objects to check in (I
think it's ok for Jonathan - as he propose me this solution on IRC, and
Marc)?

Note the code is disabled if LWIP_ARP=0 to reduce footprint...
