linux.git/net/packet, branch v2.6.26 Linux kernel source tree net: Allow netdevices to specify needed head/tailroom 2008-05-13T03:48:31+00:00 Johannes Berg johannes@sipsolutions.net 2008-05-13T03:48:31+00:00 f5184d267c1aedb9b7a8cc44e08ff6b8d382c3b5 This patch adds needed_headroom/needed_tailroom members to struct net_device and updates many places that allocate sbks to use them. Not all of them can be converted though, and I'm sure I missed some (I mostly grepped for LL_RESERVED_SPACE) Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S.
