It will be pushed if I get no objections before 01/11/19. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Thanks. Kevin Traynor --- >>From 34a4bf9093e1aec7f243aeb65a924dd04531bf48 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 13 Dec 2018 17:26:21 -0800 Subject: [PATCH] net/netvsc: fix probe when VF not found [ upstream commit f2b76d22f85694864bbcd0f88267de9ef02d75c0 ] It is possible that the VF device exists but DPDK doesn't know about it. This could happen if device was blacklisted or more likely the necessary device (Mellanox) was not part of the DPDK configuration. In either case, the right thing to do is just keep working but only with the slower para-virtual device.
