From c001c213b109c8baeeb6d012b422bf059b18368f Mon Sep 17 00:00:00 2001 From: Sathya Perla Date: Wed, 1 Jul 2009 01:06:07 +0000 Subject: be2net: fix spurious interrupt handling in intx mode Occasionally we may see an interrupt without an event in the eq. In intx, we currently see the event queue and return IRQ_NONE causing a the irq to be disabled ("no one cared".) Instead, read the CEV_ISR reg to check the existence of the interrupt.
