bnx2x: previous driver unload revised
The flow in which the bnx2x driver starts after a previous driver has been terminated in an 'unclean' manner has several bugs and FW risks, which makes it possible for the driver to fail after boot-from-SAN or kdump. This patch contains a revised flow which performs a safer initialization, solving the possible crash scenarios. Notice this patch contains lines with over 80 characters, as it keeps print-strings in a single line.
