From f88c5b9887a95ce424db629ee79b57f6ef5bfddd Mon Sep 17 00:00:00 2001 From: Sriram Date: Thu, 12 Nov 2009 02:14:38 +0000 Subject: smsc911x: Fix Console Hang when bringing the interface down. In the NAPI poll function, check for netif_running() is unnecassary. In addition to associated runtime overhead, it also results in continuous softirq loop when the interface is brought down under heavy traffic(tested with Traffic Generator).Once the interface is disabled, the poll function always returns zero(with the check for netif_running) and napi_complete() would never get called resulting in softirq loop.
