* Implemented a way to preserve header data while passing along a buffer to the upper layers: you use the store_header() function to mark the header you want to preserve. All subsequent remove_header() calls won't claim the actual data, but only move the node start around. * This header can then be restored by restore_header(). However, a call to prepend_data() will destroy the stored header. Also, if remove_header() cuts off a whole node, restoring the header won't succeed anymore. * Discarded the no longer needed net_buffer::network_header field. * Also discarded the hoplimit field which temporarily breaks the IPv6 build until Atis reworks it. * IPv4 now also dumps the IP header in the send path if debug output is enabled. * icmp_error_reply() might be called so early that the net_buffer's addresses do not point to the reply address; this is now detected, and the addresses are taken out of the IP header in that case. * Improved dumping the net_buffer to also include its address, and flags. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37688 a95241bf-73f2-0310-859d-f6bbb57e9c96

* First part of ICMP support: this is based on the work by Ivo Vachkov (GSoC 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
