bnx2x: Prevent link flaps when booting from SAN.
It is possible that the driver is configured to operate with a certain
link configuration which differs from the link's configuration during
boot from SAN - this would cause the driver to flap the link.
Said flap may be missed by specific switches, causing dcbx convergence
to be too long and boot sequence to fail. Convergence is longer because
switch ignores new dcbx packets due to counters mismatch, as only host
side reset the counters due to the link flap.
This patch causes the driver to ignore user's initial configuration during
boot from SAN, and continues with the existing link configuration.
