From 88d113601ca19c82feb038438c8c5db502d146f9 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Fri, 16 Jun 2006 12:10:46 -0700 Subject: [PATCH] [PATCH] sky2: netconsole suspend/resume interaction A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.
