From 0c4e85813d0a94eeb8bf813397a4907bdd7bb610 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 9 Oct 2007 01:36:32 -0700 Subject: [NET]: Wrap netdevice hardware header creation. Add inline for common usage of hardware header creation, and fix bug in IPV6 mcast where the assumption about negative return is an errno. Negative return from hard_header means not enough space was available,(ie -N bytes). Signed-off-by: Stephen Hemminger Signed-off-by: David S.
