From 66822b2eef8de9fe3ec9fa837386817565dbe690 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Thu, 8 Feb 2007 01:03:17 +0100 Subject: [PATCH] [ARM] 4058/2: iop32x: set ->broken_parity_status on n2100 onboard r8169 ports On the n2100, both onboard r8169 ports exhibit PCI parity problems. Set the ->broken_parity_status flag for both ports so that the r8169 drivers knows it should ignore error interrupts.
