Last Netgear's FA410TX pcmcia ethernet card and FreeBSD 4.x --- by Marc Fonvieille 12 August 2000

Last Netgear's FA410TXC cards use a new chipset, so there are detection and initialisation problems with these cards under FreeBSD.

The symptoms

Bad MAC address detection under 4.0-Release: the MAC address saw by freebsd is different from the one written on the card (it's fixed under 4.1-Release).
device timeout messages like 'ed0: device timeout'.

The solution

Correct card detection (for 4.0-R only):
The card MAC address is written on the card (Node ID), mine is 00 E0 98 7A F5 61. By default the ed driver doesn't detect the good type of card and so the correct MAC address.

To fix that we need to modify /usr/src/sys/dev/ed/if_ed.c at line 1016 we've got this:
```
    if (bcmp(test_pattern, test_buffer, sizeof(test_pattern)) == 0) {
    /* could be either an NE1000 or a Linksys ethernet controller */
        linksys = ed_get_Linksys(sc);
```
replace with:
```
    /* 
    if (bcmp(test_pattern, test_buffer, sizeof(test_pattern)) == 0) {
    */
    if (1) {
    /* could be either an NE1000 or a Linksys ethernet controller */
        linksys = ed_get_Linksys(sc);
    
```
Rebuild your kernel and reboot, now your card must be detected with correct address and type Linksys (16).

Force speed negociation:

The card seems unable to negociate link. I modified the fa_select.c used under linux to fix that problem.

Here's the code for FreeBSD:

You can find the source here: http://webperso.easynet.fr/fonvi/fa_select.c

Don't forget to change #define BASE_ADDR 0x240 with the card address.

To compile it: gcc -Wall fa_select.c -o fa_select

To use it:

    fa_select device rate
    
    where device is: ed0, ed1...
          rate is:  0       for 10BaseT
                    1       for 10Base2 (full duplex)
                    2       for 100BaseT
                    3       for 100Mbit (full duplex)

I tried this with my adsl modem (Alcatel 1000 Adsl) with fa_select ed1 0 and it runs fine without timeout. It runs fine also on my on Lan.
