I've discovered that the problem is caused by an enic device with a large number of SR-IOV virtual functions overflowing the normal sized packet buffer for netlink, leading to interfaces not being reported from an RTM_GETLINK request. The first patch here just makes the problem easier to locate if it occurs again in a different way, by adding a WARN_ON() when we run out of room in a netlink packet in this manner. The second patch actually fixes the problem, by only reporting IFLA_VF_PORTS information when the RTEXT_FILTER_VF flag is specified. v2: Corrected some CodingStyle problems ==================== Signed-off-by: David S.
