31 Originally, this driver was written for the Digital Equipment
32 Corporation series of EtherWORKS ethernet cards:
33
34 DE425 TP/COAX EISA
35 DE434 TP PCI
36 DE435 TP/COAX/AUI PCI
37 DE450 TP/COAX/AUI PCI
38 DE500 10/100 PCI Fasternet
39
40 but it will now attempt to support all cards which conform to the
41 Digital Semiconductor SROM Specification. The driver currently
42 recognises the following chips:
43
44 DC21040 (no SROM)
45 DC21041[A]
46 DC21140[A]
47 DC21142
48 DC21143
49
50 So far the driver is known to work with the following cards:
51
52 KINGSTON
53 Linksys
54 ZNYX342
55 SMC8432
56 SMC9332 (w/new SROM)
57 ZNYX31[45]
58 ZNYX346 10/100 4 port (can act as a 10/100 bridge!)
59
60 The driver has been tested on a relatively busy network using the DE425,
61 DE434, DE435 and DE500 cards and benchmarked with 'ttcp': it transferred
62 16M of data to a DECstation 5000/200 as follows:
63
64 TCP UDP
65 TX RX TX RX
66 DE425 1030k 997k 1170k 1128k
67 DE434 1063k 995k 1170k 1125k
68 DE435 1063k 995k 1170k 1125k
69 DE500 1063k 998k 1170k 1125k in 10Mb/s mode
70
71 All values are typical (in kBytes/sec) from a sample of 4 for each
72 measurement. Their error is +/-20k on a quiet (private) network and also
73 depend on what load the CPU has.
74
75 =========================================================================
76 This driver has been written substantially from scratch, although its
77 inheritance of style and stack interface from 'ewrk3.c' and in turn from
78 Donald Becker's 'lance.c' should be obvious. With the module autoload of
79 every usable DECchip board, I pinched Donald's 'next_module' field to
80 link my modules together.
81
82 Upto 15 EISA cards can be supported under this driver, limited primarily
83 by the available IRQ lines. I have checked different configurations of
84 multiple depca, EtherWORKS 3 cards and de4x5 cards and have not found a
85 problem yet (provided you have at least depca.c v0.38) ...
86
87 PCI support has been added to allow the driver to work with the DE434,
88 DE435, DE450 and DE500 cards. The I/O accesses are a bit of a kludge due
89 to the differences in the EISA and PCI CSR address offsets from the base
90 address.
91
92 The ability to load this driver as a loadable module has been included
93 and used extensively during the driver development (to save those long
94 reboot sequences). Loadable module support under PCI and EISA has been
95 achieved by letting the driver autoprobe as if it were compiled into the
96 kernel. Do make sure you're not sharing interrupts with anything that
97 cannot accommodate interrupt sharing!
98
99 To utilise this ability, you have to do 8 things:
100
101 0) have a copy of the loadable modules code installed on your system.
102 1) copy de4x5.c from the /linux/drivers/net directory to your favourite
103 temporary directory.
104 2) for fixed autoprobes (not recommended), edit the source code near
105 line 5594 to reflect the I/O address you're using, or assign these when
106 loading by:
107
108 insmod de4x5 io=0xghh where g = bus number
109 hh = device number
110
111 NB: autoprobing for modules is now supported by default. You may just
112 use:
113
114 insmod de4x5
115
116 to load all available boards. For a specific board, still use
117 the 'io=?' above.
118 3) compile de4x5.c, but include -DMODULE in the command line to ensure
119 that the correct bits are compiled (see end of source code).
120 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
121 kernel with the de4x5 configuration turned off and reboot.
122 5) insmod de4x5 [io=0xghh]
123 6) run the net startup bits for your new eth?? interface(s) manually
124 (usually /etc/rc.inet[12] at boot time).
125 7) enjoy!
126
127 To unload a module, turn off the associated interface(s)
128 'ifconfig eth?? down' then 'rmmod de4x5'.
129
130 Automedia detection is included so that in principal you can disconnect
131 from, e.g. TP, reconnect to BNC and things will still work (after a
132 pause whilst the driver figures out where its media went). My tests
133 using ping showed that it appears to work....
134
135 By default, the driver will now autodetect any DECchip based card.
136 Should you have a need to restrict the driver to DIGITAL only cards, you
137 can compile with a DEC_ONLY define, or if loading as a module, use the
138 'dec_only=1' parameter.
139
140 I've changed the timing routines to use the kernel timer and scheduling
141 functions so that the hangs and other assorted problems that occurred
142 while autosensing the media should be gone. A bonus for the DC21040
143 auto media sense algorithm is that it can now use one that is more in
144 line with the rest (the DC21040 chip doesn't have a hardware timer).
145 The downside is the 1 'jiffies' (10ms) resolution.
146
147 IEEE 802.3u MII interface code has been added in anticipation that some
148 products may use it in the future.
149
150 The SMC9332 card has a non-compliant SROM which needs fixing - I have
151 patched this driver to detect it because the SROM format used complies
152 to a previous DEC-STD format.
153
154 I have removed the buffer copies needed for receive on Intels. I cannot
155 remove them for Alphas since the Tulip hardware only does longword
156 aligned DMA transfers and the Alphas get alignment traps with non
157 longword aligned data copies (which makes them really slow). No comment.
158
159 I have added SROM decoding routines to make this driver work with any
160 card that supports the Digital Semiconductor SROM spec. This will help
161 all cards running the dc2114x series chips in particular. Cards using
162 the dc2104x chips should run correctly with the basic driver. I'm in
163 debt to <mjacob@feral.com> for the testing and feedback that helped get
164 this feature working. So far we have tested KINGSTON, SMC8432, SMC9332
165 (with the latest SROM complying with the SROM spec V3: their first was
166 broken), ZNYX342 and LinkSys. ZYNX314 (dual 21041 MAC) and ZNYX 315
167 (quad 21041 MAC) cards also appear to work despite their incorrectly
168 wired IRQs.
169
170 I have added a temporary fix for interrupt problems when some SCSI cards
171 share the same interrupt as the DECchip based cards. The problem occurs
172 because the SCSI card wants to grab the interrupt as a fast interrupt
173 (runs the service routine with interrupts turned off) vs. this card
174 which really needs to run the service routine with interrupts turned on.
175 This driver will now add the interrupt service routine as a fast
176 interrupt if it is bounced from the slow interrupt. THIS IS NOT A
177 RECOMMENDED WAY TO RUN THE DRIVER and has been done for a limited time
178 until people sort out their compatibility issues and the kernel
179 interrupt service code is fixed. YOU SHOULD SEPARATE OUT THE FAST
180 INTERRUPT CARDS FROM THE SLOW INTERRUPT CARDS to ensure that they do not
181 run on the same interrupt. PCMCIA/CardBus is another can of worms...
182
183 Finally, I think I have really fixed the module loading problem with
184 more than one DECchip based card. As a side effect, I don't mess with
185 the device structure any more which means that if more than 1 card in
186 2.0.x is installed (4 in 2.1.x), the user will have to edit
187 linux/drivers/net/Space.c to make room for them. Hence, module loading
188 is the preferred way to use this driver, since it doesn't have this
189 limitation.
190
191 Where SROM media detection is used and full duplex is specified in the
192 SROM, the feature is ignored unless lp->params.fdx is set at compile
193 time OR during a module load (insmod de4x5 args='eth??:fdx' [see
194 below]). This is because there is no way to automatically detect full
195 duplex links except through autonegotiation. When I include the
196 autonegotiation feature in the SROM autoconf code, this detection will
197 occur automatically for that case.
198
199 Command line arguments are now allowed, similar to passing arguments
200 through LILO. This will allow a per adapter board set up of full duplex
201 and media. The only lexical constraints are: the board name (dev->name)
202 appears in the list before its parameters. The list of parameters ends
203 either at the end of the parameter list or with another board name. The
204 following parameters are allowed:
205
206 fdx for full duplex
207 autosense to set the media/speed; with the following
208 sub-parameters:
209 TP, TP_NW, BNC, AUI, BNC_AUI, 100Mb, 10Mb, AUTO
210
211 Case sensitivity is important for the sub-parameters. They *must* be
212 upper case. Examples:
213
214 insmod de4x5 args='eth1:fdx autosense=BNC eth0:autosense=100Mb'.
215
216 For a compiled in driver, in linux/drivers/net/CONFIG, place e.g.
217 DE4X5_OPTS = -DDE4X5_PARM='"eth0:fdx autosense=AUI eth2:autosense=TP"'
218
219 Yes, I know full duplex isn't permissible on BNC or AUI; they're just
220 examples. By default, full duplex is turned off and AUTO is the default
221 autosense setting. In reality, I expect only the full duplex option to
222 be used. Note the use of single quotes in the two examples above and the
223 lack of commas to separate items.
