From 90893000e21e2d52a0a9d5aa0c4234c90bcd9470 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Fri, 10 Feb 2012 22:23:41 +0000 Subject: [PATCH] sfc: Generalise event generation to cover VF-owned event queues For SR-IOV we will need to send events to event queues that belong to VFs serviced by other drivers. Change the parameters of efx_generate_event() to allow this and declare it extern. While we're at it, remove the existing declaration under the wrong name efx_nic_generate_event().
