File iplink-Support-VF-Trust.patch of Package iproute2.7171
From: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com> Date: Fri, 26 Feb 2016 02:40:18 +0000 Subject: iplink: Support VF Trust Patch-mainline: v4.5.0 Git-commit: b6d77d9ee312246146e9b5ca70a8a1426898b484 References: bsc#1081176 Add IFLA_VF_TRUST message to trust the VF. PF can accept some privileged operation from the trusted VF. For example, ixgbe PF doesn't allow to enable VF promiscuous mode until the VF is trusted because it may hurt performance.
