From c4509a5ac0ace94d5b1f0092dc4d36933c1d896e Mon Sep 17 00:00:00 2001 From: Haiyang Zhang Date: Wed, 30 Oct 2019 15:32:11 +0000 Subject: [PATCH] hv_netvsc: Fix error handling in netvsc_set_features() When an error is returned by rndis_filter_set_offload_params(), we should still assign the unaffected features to ndev->features. Otherwise, these features will be missing. Fixes: d6792a5a0747 ("hv_netvsc: Add handler for LRO setting change") Signed-off-by: Haiyang Zhang Signed-off-by: David S.
