I tried several 5702 NICs with various revisions and was never able to
duplicate the problem you're seeing. They all worked correctly with my
first patch.
Can you test the attached patch? I've simply removed the test
altogether.
The Linux driver doesn't perform this test and the fact that the test is
performed after bge_reset() is called simply means we're checking the
same
information twice (i.e. did the NIC firmware load). Since the firmware
handshake was successful we know the firmware loaded so the test is
redundant.
