From f83f1768f833cb45bc93429fdc552252a4f55ac3 Mon Sep 17 00:00:00 2001 From: Joonwoo Park Date: Mon, 31 Mar 2008 21:02:47 -0700 Subject: [LLC]: skb allocation size for responses Allocate the skb for llc responses with the received packet size by using the size adjustable llc_frame_alloc. Don't allocate useless extra payload. Cleanup magic numbers. So, this fixes oops.
