From 27660515a21bf913e3208ded3f27abd0529fae0e Mon Sep 17 00:00:00 2001 From: Michał Mirosław Date: Fri, 18 Mar 2011 16:56:34 +0000 Subject: net: implement dev_disable_lro() hw_features compatibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement compatibility with new hw_features for dev_disable_lro(). This is a transition path - dev_disable_lro() should be later integrated into netdev_fix_features() after all drivers are converted. Signed-off-by: Michał Mirosław Signed-off-by: David S.
