commit ba504994 upstream. macb_interrupt() should not use macb_writel(bp, ISR, <value>) but only queue_writel(queue, ISR, <value>). There is one IRQ and one set of {ISR, IER, IDR, IMR} [1] registers per queue on gem hardware, though only queue0 is actually used for now to receive frames: other queues can already be used to transmit frames. The queue_readl() and queue_writel() helper macros are designed to access the relevant IRQ registers. [1] ISR: Interrupt Status Register IER: Interrupt Enable Register IDR: Interrupt Disable Register IMR: Interrupt Mask Register Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Fixes: bfbb92c4 ("net: macb: Handle the RXUBR interrupt on all devices") Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: David S.
