The de driver for stable will not select full-duplex on some (all?)
cards with MII transceivers. I posted a patch for the DLINK 570TX
quad port card that may work with other 21143/MII cards. I don't
have the patch handy at the moment, check the list archives if
anyone is interested.

Hi,
Many thanks for the pointer! I'm going to give this a try. It

Yes. I have to interface to an existing system that is encrypting its data

ECB format. Thanks for the info, by the way I found the ecb_crypt by doing
a

Hi folks,
I'm looking for an explanation of a difference I've found between NetBSD
and FreeBSD in the handling of arithmetic overflow in typecasting.
The following code, compiled on a stock FreeBSD 4.0-CURRENT machine
cores on SIGFPE. On a NetBSD 1.4.1 machine (gcc-2.91.60), the program
prints
Hi all,
I was working a couple of days to have a small as possible kernel in
FreeBSD 3.3 Release. Well coud somebody point me to some docs about this
subject ?
Does anybody know real procedures, steps whatever to keep a small an
efficient kernel ?
thanks,
Stef

Theo,
Though doug didn't say so, I think the equivalent code in freeBSD is
if ((fd = open("/dev/io",O_RDWR,0)) == -1) {
ERROR...
}
you are asking for permission to do direct IO to IO ports from userland.
