From ce9e76c8450fc248d3e1fc16ef05e6eb50c02fa5 Mon Sep 17 00:00:00 2001 From: Jarek Poplawski Date: Thu, 5 Aug 2010 01:19:11 +0000 Subject: net: Fix napi_gro_frags vs netpoll path The netpoll_rx_on() check in __napi_gro_receive() skips part of the "common" GRO_NORMAL path, especially "pull:" in dev_gro_receive(), where at least eth header should be copied for entirely paged skbs.
