This is a common low-cost OEM pocket ethernet - adapter, sold under many names. - - Sources: - This driver was written from the packet driver assembly code provided by - Vincent Bono of AT-Lan-Tec. Ever try to figure out how a complicated - device works just from the assembly code? It ain't pretty. The following - description is written based on guesses and writing lots of special-purpose - code to test my theorized operation. - - In 1997 Realtek made available the documentation for the second generation - RTL8012 chip, which has lead to several driver improvements. - http://www.realtek.com.tw/ - - Theory of Operation - - The RTL8002 adapter seems to be built around a custom spin of the SEEQ - controller core. It probably has a 16K or 64K internal packet buffer, of - which the first 4K is devoted to transmit and the rest to receive. - The controller maintains the queue of received packet and the packet buffer - access pointer internally, with only 'reset to beginning' and 'skip to next - packet' commands visible. The transmit packet queue holds two (or more?) - packets: both 'retransmit this packet' (due to collision) and 'transmit next - packet' commands must be started by hand. - - The station address is stored in a standard bit-serial EEPROM which must be - read (ughh) by the device driver. (Provisions have been made for - substituting a 74S288 PROM, but I haven't gotten reports of any models - using it.) Unlike built-in devices, a pocket adapter can temporarily lose - power without indication to the device driver. The major effect is that - the station address, receive filter (promiscuous, etc.) and transceiver - must be reset. - - The controller itself has 16 registers, some of which use only the lower - bits. The registers are read and written 4 bits at a time. The four bit - register address is presented on the data lines along with a few additional - timing and control bits. The data is then read from status port or written - to the data port. - - Correction: the controller has two banks of 16 registers. The second - bank contains only the multicast filter table (now used) and the EEPROM - access registers. - - Since the bulk data transfer of the actual packets through the slow - parallel port dominates the driver's running time, four distinct data - (non-register) transfer modes are provided by the adapter, two in each - direction. In the first mode timing for the nibble transfers is - provided through the data port. In the second mode the same timing is - provided through the control port. In either case the data is read from - the status port and written to the data port, just as it is accessing - registers. - - In addition to the basic data transfer methods, several more are modes are - created by adding some delay by doing multiple reads of the data to allow - it to stabilize. This delay seems to be needed on most machines. - - The data transfer mode is stored in the 'dev->if_port' field. Its default - value is '4'. It may be overridden at boot-time using the third parameter - to the "ether=..." initialization. - - The header file <atp.h> provides inline functions that encapsulate the - register and data access methods. These functions are hand-tuned to - generate reasonable object code. This header file also documents my - interpretations of the device registers. -*/ - -#include <linux/kernel.h> -#include <linux/module.h> -#include <linux/types.h> -#include <linux/fcntl.h> -#include <linux/interrupt.h> -#include <linux/ioport.h> -#include <linux/in.h> -#include <linux/string.h> -#include <linux/errno.h> -#include <linux/init.h> -#include <linux/crc32.h> -#include <linux/netdevice.h> -#include <linux/etherdevice.h> -#include <linux/skbuff.h> -#include <linux/spinlock.h> -#include <linux/delay.h> -#include <linux/bitops.h> - -#include <asm/io.h> -#include <asm/dma.h> - -#include "atp.h" - -MODULE_AUTHOR("Donald Becker <becker@scyld.com>"); -MODULE_DESCRIPTION("RealTek RTL8002/8012 parallel port Ethernet driver"); -MODULE_LICENSE("GPL"); - -module_param(max_interrupt_work, int, 0); -module_param(debug, int, 0); -module_param_array(io, int, NULL, 0); -module_param_array(irq, int, NULL, 0); -module_param_array(xcvr, int, NULL, 0); -MODULE_PARM_DESC(max_interrupt_work, "ATP maximum events handled per interrupt"); -MODULE_PARM_DESC(debug, "ATP debug level (0-7)"); -MODULE_PARM_DESC(io, "ATP I/O base address(es)"); -MODULE_PARM_DESC(irq, "ATP IRQ number(s)"); -MODULE_PARM_DESC(xcvr, "ATP transceiver(s) (0=internal, 1=external)"); - -/* The number of low I/O ports used by the ethercard. */ -#define ETHERCARD_TOTAL_SIZE 3 - -/* Sequence to switch an 8012 from printer mux to ethernet mode. */ -static char mux_8012[] = { 0xff, 0xf7, 0xff, 0xfb, 0xf3, 0xfb, 0xff, 0xf7,}; - -struct net_local { - spinlock_t lock; - struct net_device *next_module; - struct timer_list timer; /* Media selection timer. */ - long last_rx_time; /* Last Rx, in jiffies, to handle Rx hang. */ - int saved_tx_size; - unsigned int tx_unit_busy:1; - unsigned char re_tx, /* Number of packet retransmissions. */ - addr_mode, /* Current Rx filter e.g. promiscuous, etc. */ - pac_cnt_in_tx_buf, - chip_type; -}; - -/* This code, written by wwc@super.org, resets the adapter every - TIMED_CHECKER ticks.
