From 06be580ac7b650938cb3f2cf8cd02d73ff96d3e4 Mon Sep 17 00:00:00 2001 From: Haiyang Zhang Date: Fri, 1 Sep 2017 14:30:06 -0700 Subject: hv_netvsc: Simplify the limit check in netvsc_set_channels() Because of the following code, net->num_tx_queues equals to VRSS_CHANNEL_MAX, and max_chn is less than or equals to VRSS_CHANNEL_MAX. netvsc_drv.c: alloc_etherdev_mq(sizeof(struct net_device_context), VRSS_CHANNEL_MAX); rndis_filter.c: net_device->max_chn = min_t(u32, VRSS_CHANNEL_MAX, num_possible_rss_qs); So this patch removes the unnecessary limit check before comparing with "max_chn".
