From: Kazuya Mizuguchi <[email protected]> AVB-DMAC Receive FIFO Warning interrupt is not enabled, so it is not necessary to disable the interrupt in ndo_close(). On the other hand, this patch disables the interrupt in ndo_open() to prevent the possibility that the interrupt is issued by the state that a boot loader left.
