2007), and Yin Qiu (GSoC 2008). And even though I needed to rewrite pretty much all of it because of the countless bugs and problems it had, it still shares the same architectural problems of introducing a domain dependent error mechanism to the upper layers, and needing the net_buffer::network_header hack. This I will rework later. * net_buffer's append_size(), and prepend_size() will now gracefully handle buffers without a data node. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37647 a95241bf-73f2-0310-859d-f6bbb57e9c96
