Summary
net: ethernet: mtk-star-emac: fix spinlock recursion issues on rx/tx poll
Details

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: mtk-star-emac: fix spinlock recursion issues on rx/tx poll

Use spinlockirqsave and spinunlockirqrestore instead of spinlock and spinunlock in mtkstaremac driver to avoid spinlock recursion occurrence that can happen when enabling the DMA interrupts again in rx/tx poll.

BUG: spinlock recursion on CPU#0, swapper/0/0
