From ceb27759987ec10ba22332bd7fdf1cfb35b86991 Mon Sep 17 00:00:00 2001 From: Shota Suzuki Date: Fri, 11 Dec 2015 18:43:59 +0900 Subject: [PATCH] igb: Remove unnecessary flag setting in igb_set_flag_queue_pairs() If VFs are enabled (max_vfs >= 1), both max_rss_queues and adapter->rss_queues are set to 2 in the case of e1000_82576. In this case, IGB_FLAG_QUEUE_PAIRS is always set in the default block as a result of fall-through, thus setting it in the e1000_82576 block is not necessary.
