From 3e1d7cd2dc708f2054b2180e05ae283b9f91d543 Mon Sep 17 00:00:00 2001 From: Wang Chen Date: Wed, 3 Dec 2008 22:07:10 -0800 Subject: [PATCH] e1000: e1000_adapter->polling_netdev is useless Commit bea3348eef27e6044b6161fd04c3152215f96411 "[NET]: Make NAPI polling independent of struct net_device objects." made NAPI polling to be independent of net_device. So e1000_adapter->polling_netdev is no longer used. Kill it. Signed-off-by: Wang Chen Signed-off-by: David S.
