Otherwise, an unexpected recursive fenced PHB error is observed. 0001:06:00.0 Ethernet controller: Broadcom Corporation \ NetXtreme BCM5718 Gigabit Ethernet PCIe (rev 10) 0001:06:00.1 Ethernet controller: Broadcom Corporation \ NetXtreme BCM5718 Gigabit Ethernet PCIe (rev 10) Signed-off-by: Gavin Shan Signed-off-by: Michael Ellerman --- diff --git a/arch/powerpc/platforms/powernv/eeh-powernv.c b/arch/powerpc/platforms/powernv/eeh-powernv.c index d2f19821d71d..d12ea7b9fd47 100644 --- a/arch/powerpc/platforms/powernv/eeh-powernv.c +++ b/arch/powerpc/platforms/powernv/eeh-powernv.c @@ -412,11 +412,14 @@ static void *pnv_eeh_probe(struct pci_dn *pdn, void *data) * been set for the PE, we will set EEH_PE_CFG_BLOCKED for * that PE to block its config space. * + * Broadcom BCM5718 2-ports NICs (14e4:1656) * Broadcom Austin 4-ports NICs (14e4:1657) * Broadcom Shiner 4-ports 1G NICs (14e4:168a) * Broadcom Shiner 2-ports 10G NICs (14e4:168e) */ if ((pdn->vendor_id == PCI_VENDOR_ID_BROADCOM && + pdn->device_id == 0x1656) || + (pdn->vendor_id == PCI_VENDOR_ID_BROADCOM && pdn->device_id == 0x1657) || (pdn->vendor_id == PCI_VENDOR_ID_BROADCOM && pdn->device_id == 0x168a) ||
