From 08348995c47ec0e6ad3712c08eb88fb4df2e8180 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 16 Nov 2016 15:10:49 +0100 Subject: [PATCH] netronome: don't access real_num_rx_queues directly The netdev->real_num_rx_queues setting is only available if CONFIG_SYSFS is enabled, so we now get a build failure when that is turned off: netronome/nfp/nfp_net_common.c: In function 'nfp_net_ring_swap_enable': netronome/nfp/nfp_net_common.c:2489:18: error: 'struct net_device' has no member named 'real_num_rx_queues'; did you mean 'real_num_tx_queues'? As far as I can tell, the check here is only used as an optimization that we can skip in order to fix the compilation. If sysfs is disabled, the following netif_set_real_num_rx_queues() has no effect.
