From 17ba15fb6264f27374bc87f4c3f8519b80289d85 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 27 Dec 2005 20:57:40 -0800 Subject: [PATCH] [PPPOX]: Fix assignment into const proto_ops. And actually, with this, the whole pppox layer can basically be removed and subsumed into pppoe.c, no other pppox sub-protocol implementation exists and we've had this thing for at least 4 years.
