From fe13dda2d24eca2ee8a6bb8a0af88ab84d589fd6 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Tue, 15 Apr 2008 19:03:23 -0700 Subject: [PATCH] [TIPC]: Force linearization of non-linear sk_buffs This patch allows TIPC to process incoming messages that are stored in a fragmented sk_buff, by forcing the linearization of any such messages it receives. Note: This is an interim solution to allow TIPC to operate with Ethernet devices that generate non-linear buffers (such as the gianfar driver), until such time as the rest of TIPC is enhanced to handle sk_buffs with multiple data areas.
