eth_rx() in the main reception loop may trigger sending a packet which
is already timed out (or will immediately) upon reception of an ARP reply.
As long as the ARP reply is pending, the timeout handler of a packet
should be postponed.
Happens on TFTP with bad network (e.g. WLAN).Signed-off-by: Stefan Brüns

A number of network related files were imported from the LiMon
project; these contain a somewhat unclear license statement:Copyright 1994 - 2000 Neil Russell.
(See License)I analyzed the source code of LiMon v1.4.2 which was used for this
import. It does not contain any "License" file, but the top level
directory contains a file "COPYING", which turns out to be GPL v2
of June 1991. So it is legitimate to conclude that the LiMon derived
files are also to be released under GPLv2. Mark them as such.Signed-off-by: Wolfgang Denk

Add several levels of DEBUG prints so that you can limit the noise to
the severety of your problem.DEBUG_LL_STATE = Link local state machine changes
DEBUG_DEV_PKT = Packets or info directed to the device
DEBUG_NET_PKT = Packets on info on the network at large
DEBUG_INT_STATE = Internal network state changesSigned-off-by: Joe Hershberger

Cisco's arp-proxy feature fails to ignore the link-local address range
This means that a link-local device on a network with this Cisco
equipment will reply to ARP requests for our device (in addition to
our reply).
If we happen to reply first, the requester's ARP table will be
populated with our MAC address, and one packet will be sent to us...
shortly following this, the requester will get an ARP reply from the
Cisco equipment telling the requester to send packets their way
instead of to our device from now on.
This work-around detects this link-local condition and will delay
replying to the ARP request for 5ms so that the first packet is sent
to the Cisco equipment and all following packets are sent to our
device.Signed-off-by: Joe Hershberger
