From d7b06636be162d3f74c9ce5d6d0d9ea4e5d362c8 Mon Sep 17 00:00:00 2001 From: Peter P Waskiewicz Jr Date: Fri, 26 Dec 2008 01:35:35 -0800 Subject: [PATCH] net: Init NAPI dev_list on napi_del The recent GRO patches introduced the NAPI removal of devices in free_netdev. For drivers that can change the number of queues during driver operation, the NAPI infrastructure doesn't allow the freeing and re-addition of NAPI entities without reloading the driver. This change reinitializes the dev_list in each NAPI struct on delete, instead of just deleting it (and assigning the list pointers to POISON). Drivers that wish to remove/re-add NAPI will need to re-initialize the netdev napi_list after removing all NAPI instances, before re-adding NAPI devices again.
