Qlogic chip will not attempt to transmit the frame until it has been
completely transferred over PCI, according to the QL engineer.=20

Hi Jeff,

=20

You're correct.  The PCI & FC interfaces operate asynchronously within
the chip.   So it will not attempt to transmit the frame until it has
been completely transferred over PCI
Also, attached is the 4.3.0 code.

-Rob.

Rob,

I still have some thing to try on the LOS.  I can try a 2300 based
system and also try different analyzer ports.  I would like to have
tried these before you bring your Finisar.  All the same if there is a
particularly convenient time for you, please let me know.

=20

One more question - am I correct in guessing that a whole frame is read
into the frame buffer before beginning a transmission on the fibre?
There is not any possibility of any sort of underrun if the PCI bus is
very busy or slow, right?

=20

Thanks,

Jeff

Jeff,

=20

Not sure what's causing that analyzer to see a LOS.  Would be nice to
get another analyzer to verify.  I may be able to come up for a day with
one of our Finisar boxes.  Let me know if you agree it would be a good
idea and we can work out a schedule.

Attached is the latest 2432 errata.
