From 51363b8751a673a00ad48eea895266396d53fa52 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Wed, 8 Feb 2012 00:19:48 +0000 Subject: af_iucv: allow retrieval of maximum message size For HS transport the maximum message size depends on the MTU-size of the HS-device bound to the AF_IUCV socket. This patch adds a getsockopt option MSGSIZE returning the maximum message size that can be handled for this AF_IUCV socket.
