I don't know exactly which patch resolved this issue. The driver went over quite a bit of rework so it's unlikely that the change will be small or simple. Although you can go over the drivers from SF and find the closest version to 2.17.12 that solves your issue and look at the changes. >In case of updating the driver, only updating ixgbevf alone >is enough OR I need to update both ixgbe and ixgbevf ?? We test the ixgbe and ixgbevf together as they are released, so the further away ixgbevf is from ixgbe the more likely you are to run into some kind of problem. >Is there any dependency with user land packages (related to >nettools or something related) ??
