From 91e83133e70ebe1572746d1ad858b4eb28ab9b53 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 5 Feb 2015 14:58:14 -0800 Subject: net: use netif_rx_ni() from process context Hotpluging a cpu might be rare, yet we have to use proper handlers when taking over packets found in backlog queues. dev_cpu_callback() runs from process context, thus we should call netif_rx_ni() to properly invoke softirq handler.
