From 3fdadf7d27e3fbcf72930941884387d1f4936f04 Mon Sep 17 00:00:00 2001 From: Dmitry Mishin Date: Mon, 20 Mar 2006 22:45:21 -0800 Subject: [NET]: {get|set}sockopt compatibility layer This patch extends {get|set}sockopt compatibility layer in order to move protocol specific parts to their place and avoid huge universal net/compat.c file in the future.
