From c0b46d8ead3c6c5b569c83544fd71b9d73356869 Mon Sep 17 00:00:00 2001 From: James Clough Date: Thu, 10 Sep 2009 09:11:50 +0200 Subject: net: Fix problem with 405EZ ethernet interrupt On 405EZ the RX-/TX-interrupts are coalesced into one IRQ bit in the UIC. We need to acknowledge the RX-/TX-interrupts in the SDR0_ICINTSTAT reg as well.
