From de509f9f08726077ffd2f2d5e4b63e17cb516938 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Thu, 7 Jun 2012 10:30:59 +0200 Subject: [PATCH] PCI: add Chelsio T310 10GbE NIC broken INTx masking quirk According to http://thread.gmane.org/gmane.comp.emulators.kvm.devel/91388 the T310 does not properly support INTx masking as it fails to keep the PCI_STATUS_INTERRUPT bit updated once the interrupt is masked. Mark this adapter as broken so that pci_intx_mask_supported won't report it as compatible.
