> This patch fixes link status update problem in interrupt mode.
> Previously, directly reading link status register instead of accessing via admin
> queue command may cause the link status change interrupt callback inactive.
> This patch fixes the problem by making the driver only read the register in
> "no wait" and polling mode.
