From 188313c137c4f76afd0862f50dbc185b198b9e2a Mon Sep 17 00:00:00 2001 From: Toshiaki Makita Date: Tue, 29 Jan 2019 09:45:55 +0900 Subject: virtio_net: Fix not restoring real_num_rx_queues When _virtnet_set_queues() failed we did not restore real_num_rx_queues. Fix this by placing the change of real_num_rx_queues after _virtnet_set_queues(). This order is also in line with virtnet_set_channels().
