bnxt_en: Add async event handling for speed config changes.
On some dual port cards, link speeds on both ports have to be compatible. Firmware will inform the driver when a certain speed is no longer supported if the other port has linked up at a certain speed. Add logic to handle this event by logging a message and getting the updated list of supported speeds. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.
