From cb59bfd419d0c560b9f7273522f9a4799062aad5 Mon Sep 17 00:00:00 2001 From: Shay Drory Date: Mon, 3 Aug 2026 12:00:12 +0300 Subject: [PATCH] devlink: Expose external flag for PCI SF ports The external flag is part of the PCI SF port attributes, but unlike the PCI PF and PCI VF flavours it was never filled into the port dump, so userspace could not query it directly. Reporting of the external flag was missed for SF ports. Hence, put DEVLINK_ATTR_PORT_EXTERNAL for the PCI SF flavour as well, matching what PCI PF and PCI VF ports already report. $ devlink port show pci/0033:01:00.0/163840 pci/0033:01:00.0/163840: type eth netdev eth1 flavour pcisf controller 1 pfnum 0 sfnum 77 external true splittable false Reviewed-by: Parav Pandit Signed-off-by: Shay Drory Link: https://patch.msgid.link/20260803090012.257242-1-shayd@nvidia.com Signed-off-by: Jakub Kicinski --- net/devlink/port.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/net/devlink/port.c b/net/devlink/port.c index dc82cac68e7d..1528f2d148df 100644 --- a/net/devlink/port.c +++ b/net/devlink/port.c @@ -267,6 +267,8 @@ static int devlink_nl_port_attrs_put(struct sk_buff *msg, nla_put_u32(msg, DEVLINK_ATTR_PORT_PCI_SF_NUMBER, attrs->pci_sf.sf)) return -EMSGSIZE; + if (nla_put_u8(msg, DEVLINK_ATTR_PORT_EXTERNAL, attrs->pci_sf.external)) + return -EMSGSIZE; break; case DEVLINK_PORT_FLAVOUR_PHYSICAL: case DEVLINK_PORT_FLAVOUR_CPU:
