I have a 3com3c595-TX card on a FBSD2.5.1 system. Upon bootup the message
says its an early version card.
The drivers say this:
/*
* Check for receive overrun anomaly in the first revision of the
* adapters.
*/
if(!(get_e(unit, EEPROM_SOFT_INFO_2) & NO_RX_OVN_ANOMALY)) {
printf("Warning! Defective early revision adapter!\n");
}
Considering I just purchased this card, I don't think its an early
version ( unless they had bad stock ).
In any case, I'm experiencing data throughput problems:
In an FTP test, sometimes I can get 300-400Kb/s ( a sparc 10 to a sparc 20
does about 450-550 on the same network ). However, after I try to do the
same FTP again, or any subsequent ones, the data rate drops to 1.9k!!
After several hours the problem goes away, but as soon as I transfer something
again, the rate drops down to below 14.4 baud rates!
Is this the problem described above or is there some major problem
with the networking code on 2.5.1.
Also, what is a good 100Mb card for FBSD? I would just use a 509 (10Mb) card
but the kernel config files say the driver is buggy. I need a very reliable
network card/driver combination.
Also, I heard the 595's were just discontinued and the 905 is to replace it.
Anybody working on an alpha driver?
