cxgb4 probe can take up to over 1 minute when the firmware is
is written and installed on the device, even after this the device
driver still does some device probing and can take quite a bit.
systemd will kill this driver when probe does take over 30 seconds,
use the asynch probe mechanism to circumvent this.
