| 11 | Information and Code Sources: |
| 12 | |
| 13 | 1) The existing myriad of Linux 8390 drivers written by Donald Becker. |
| 14 | |
| 15 | 2) Once again Russ Nelson's asm packet driver provided additional info. |
| 16 | |
| 17 | 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg files. |
| 18 | Too bad it doesn't work -- see below. |
| 19 | |
| 20 | The ES3210 is an EISA shared memory NS8390 implementation. Note |
| 21 | that all memory copies to/from the board must be 32bit transfers. |
| 22 | Which rules out using eth_io_copy_and_sum() in this driver. |
| 23 | |
| 24 | Apparently there are two slightly different revisions of the |
| 25 | card, since there are two distinct EISA cfg files (!rii0101.cfg |
| 26 | and !rii0102.cfg) One has media select in the cfg file and the |
| 27 | other doesn't. Hopefully this will work with either. |
| 28 | |
| 29 | That is about all I can tell you about it, having never actually |
| 30 | even seen one of these cards. :) Try http://www.interlan.com |
| 31 | if you want more info. |
| 32 | |
| 33 | Thanks go to Mark Salazar for testing v0.02 of this driver. |
| 34 | |
| 35 | Bugs, to-fix, etc: |
| 36 | |
| 37 | 1) The EISA cfg ports that are *supposed* to have the IRQ and shared |
| 38 | mem values just read 0xff all the time. Hrrmpf. Apparently the |
| 39 | same happens with the packet driver as the code for reading |
| 40 | these registers is disabled there. In the meantime, boot with: |
| 41 | ether=<IRQ>,0,0x<shared_mem_addr>,eth0 to override the IRQ and |
| 42 | shared memory detection. (The i/o port detection is okay.) |
| 43 | |
| 44 | 2) Module support currently untested. Probably works though. |
