From 21d05db175202adb166b047f35cbb96dbf9b86a5 Mon Sep 17 00:00:00 2001 From: Brice Goglin Date: Tue, 9 Jan 2007 21:05:04 +0100 Subject: [PATCH] myri10ge: check that we can get an irq Now that IRQ allocation is done in myri10ge_open(), we want to still check when loading the driver that IRQ allocation could succeed later. Additionaly, we fix the initialization and printing of netdev->irq.
