[libvirt] [PATCH 3/3 RFC] macvtap: Fix getPhysfn to get the PF of a direct attach network interface

From: Roopa Prabhu <roprabhu(a)cisco.com&gt; This patch adds code to the existing getPhysfn to get the PF device name and VF index if the linkdev is a sriov VF. The idea is to send the port profile message to a PF if the direct attach interface is a VF. Eventually interface.c is probably the right place for getPhysfn Signed-off-by: Roopa Prabhu <roprabhu(a)cisco.com&gt; Signed-off-by: Christian Benvenuti <benve(a)cisco.com&gt; Signed-off-by: David Wang <dwang2(a)cisco.com&gt; --- src/util/macvtap.c | 15 ++++++--------- 1 files changed, 6 insertions(+), 9 deletions(-) diff --git a/src/util/macvtap.c b/src/util/macvtap.c index 0b00776..7fcea0d 100644 --- a/src/util/macvtap.c +++ b/src/util/macvtap.c @@ -948,18 +948,15 @@ getPhysfn(const char *linkdev, char **physfndev) { int rc = 0; - bool virtfn = false; - if (virtfn) { + if (ifaceIsVF(linkdev)) { - /* XXX: if linkdev is SR-IOV VF, then set vf = VF index */ - /* XXX: and set linkdev = PF device */ - /* XXX: need to use get_physical_function_linux() or */ - /* XXX: something like that to get PF */ - /* XXX: device and figure out VF index */ - - rc = 1; + /* if linkdev is SR-IOV VF, then set vf = VF index */ + /* and set physfndev = PF device */ + rc = ifaceGetPFName(linkdev, physfndev); + if (!rc) + rc = ifaceGetVFIndex(*physfndev, linkdev, vf); } else { /* Not SR-IOV VF: physfndev is linkdev and VF index
