[ixp1200] Problems with Diagnostics...

[Heaton, Eric D]

Austen,

I believe that you are running the version of the diags with the Gigabit
loopback bug.. v1.2.76.  The first patch for this fix would have been in
build v1.2D.77, as well as incorporated into v1.3.141 software.

Please make sure you are compiling and flashing the latest diags and let us
know if you are still having problems.

	We at Tech are trying to debug some problems with our gigabit
ports: they've seemed to stop working (sending and recv'ing) suddenly and
there appears to be no reason for it. So, we decided to turn to the
diagnositcs.
	We updated the diagnostics (b/c the old version has known gigabit
problems) as per the release notes in SDK v1.3: we reinstalled the boot
image boot1200.bin overwriting everything and installing Diagnostics
v1.2.76.
	When we run the diagnostics, they fail on the gigabit tests;
nothing is sent or received except in one case: if the first thing you do
when you run the diagnostics is gigabit, internal loopback mode, run test
continuously, then 16 packets are sent--after that nothing and if you go
do something else (like an octal test or external loopback test) before
you try this test, nothing happens. However, the octal tests work. Does
anyone have any suggestions?
