From 09f75cd7bf13720738e6a196cc0107ce9a5bd5a0 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Wed, 3 Oct 2007 17:41:50 -0700 Subject: [NET] drivers/net: statistics cleanup #1 -- save memory and shrink code We now have struct net_device_stats embedded in struct net_device, and the default ->get_stats() hook does the obvious thing for us. Run through drivers/net/* and remove the driver-local storage of statistics, and driver-local ->get_stats() hook where applicable. This was just the low-hanging fruit in drivers/net; plenty more drivers remain to be updated.
