SYSLIB CHANGES: - DS calls to publish / retrieve labels consider endpoints instead of u32_t. VFS CHANGES: - mapdriver() only adds an entry in the dmap table in VFS. - dev_up() is only executed upon reception of a driver up event. INET CHANGES: - INET no longer searches for existing drivers instances at startup. - A newtwork driver is (re)initialized upon reception of a driver up event. - Networking startup is now race-free by design. No need to waste 5 seconds at startup any more. DRIVER CHANGES: - Every driver publishes driver up events when starting for the first time or in case of restart when recovery actions must be taken in the upper layers. - Driver up events are published by drivers through DS. - For regular drivers, VFS is normally the only subscriber, but not necessarily. For instance, when the filter driver is in use, it must subscribe to driver up events to initiate recovery. - For network drivers, inet is the only subscriber for now. - Every VFS driver is statically linked with libdriver, every network driver is statically linked with libnetdriver. DRIVER LIBRARIES CHANGES: - Libdriver is extended to provide generic receive() and ds_publish() interfaces for VFS drivers. - driver_receive() is a wrapper for sef_receive() also used in driver_task() to discard spurious messages that were meant to be delivered to a previous version of the driver. - driver_receive_mq() is the same as driver_receive() but integrates support for queued messages. - driver_announce() publishes a driver up event for VFS drivers and marks the driver as initialized and expecting a DEV_OPEN message. - Libnetdriver is introduced to provide similar receive() and ds_publish() interfaces for network drivers (netdriver_announce() and netdriver_receive()). - Network drivers all support live update with no state transfer now. KERNEL CHANGES: - Added kernel call statectl for state management. Used by driver_announce() to unblock eventual callers sendrecing to the driver. |

This is my implementation of a new network task for the Minix kernel. I did it initially to handle a 3c501 board (Etherlink), but those board are so unstable that it is not worth using them except for learning how to implement a driver. When I got a 3c509b board (Etherlink III) it was easier to write the code to handle them. The Minix code in 'dp8390.c' is too specific for the National chip set, so what I did was to remove as much as I needed of the code dependant from the chip and produce a generic task that, I hope, will be able to handle many more cards. $Log$ Revision 1.1 2005/06/29 10:16:46 beng Import of dpeth 3c501/3c509b/.. ethernet driver by Giovanni Falzoni <fgalzoni@inwind.it>. Revision 1.3 2004/04/14 12:49:07 lsodgf0 Changes for porting to Minix 2.0.4 run on BOCHS Revision 1.2 2002/03/25 14:16:09 lsodgf0 The driver for the NEx000 has been rewritten to be operational with the ACCTON 18xx (an NE1000 clone) The I/O routines for 16 bit cards are still untested.. Revision 1.1 2002/02/09 09:35:09 lsodgf0 Initial revision The package is not fully tested, i.e. I had only 3Com boards (3c501, 3c503, 3c503/16 and 3c509b) and WD8003. I got also a NE1000 clone but it was not fully operational and I could not appreciate the results. For this reason the changes done to the interface to I/O for 8 and 16 bits are not tested. $Id$
