| 14 | - ICL EtherTeam 16i |
Jeff Garzik | 6aa20a2 | 2006-09-13 13:24:59 -0400 | [diff] [blame] | 15 | - ICL EtherTeam 32 EISA |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 16 | (Uses true 32 bit transfers rather than 16i compability mode) |
| 17 | |
| 18 | Example Module usage: |
| 19 | insmod eth16i.o io=0x2a0 mediatype=bnc |
| 20 | |
| 21 | mediatype can be one of the following: bnc,tp,dix,auto,eprom |
| 22 | |
| 23 | 'auto' will try to autoprobe mediatype. |
| 24 | 'eprom' will use whatever type defined in eprom. |
| 25 | |
| 26 | I have benchmarked driver with PII/300Mhz as a ftp client |
| 27 | and 486/33Mhz as a ftp server. Top speed was 1128.37 kilobytes/sec. |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 126 | |
| 127 | Bugs: |
Jeff Garzik | 6aa20a2 | 2006-09-13 13:24:59 -0400 | [diff] [blame] | 128 | In some cases the media interface autoprobing code doesn't find |
| 129 | the correct interface type. In this case you can |
| 130 | manually choose the interface type in DOS with E16IC.EXE which is |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 131 | configuration software for EtherTeam16i and EtherTeam32 cards. |
| 132 | This is also true for IRQ setting. You cannot use module |
Jeff Garzik | 6aa20a2 | 2006-09-13 13:24:59 -0400 | [diff] [blame] | 133 | parameter to configure IRQ of the card (yet). |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 134 | |
| 135 | To do: |
| 136 | - Real multicast support |
| 137 | - Rewrite the media interface autoprobing code. Its _horrible_ ! |
| 138 | - Possibly merge all the MB86965 specific code to external |
| 139 | module for use by eth16.c and Donald's at1700.c |
| 140 | - IRQ configuration with module parameter. I will do |
| 141 | this when i will get enough info about setting |
| 142 | irq without configuration utility. |
