Hello!
I know this driver is sloppy.. but, is anyone interested in collaborating with me to fix that it on the Alpha?
It sometimes works, but very ocassionally.. really weird behaviour, both with NAPI and without.

Seriously, have a look at http://people.freebsd.org/~wpaul/re/if_re.c
| Quote: | * The following routine is designed to test for a defect on some
* 32-bit 8169 cards. Some of these NICs have the REQ64# and ACK64#
* lines connected to the bus, however for a 32-bit only card, they
* should be pulled high. The result of this defect is that the
* NIC will not work right if you plug it into a 64-bit slot: DMA
* operations will be done with 64-bit transfers, which will fail
* because the 64-bit data lines aren't connected.
*
* There's no way to work around this (short of talking a soldering
* iron to the board), however we can detect it. The method we use
* here is to put the NIC into digital loopback mode, set the receiver
* to promiscuous mode, and then try to send a frame. We then compare
* the frame data we sent to what was received. If the data matches,
* then the NIC is working correctly, otherwise we know the user has
* a defective NIC which has been mistakenly plugged into a 64-bit PCI
* slot. In the latter case, there's no way the NIC can work correctly,
* so we print out a message on the console and abort the device attach.

When I found this notice it gave me the creeps. Also notice the 7500 byte limitation for Jumbo packages. And so on. This NIC is a few years old by now and it is still not working. That is why I came to the final conclusion. The DS20 is a fine machine (I have a few myself). Compaq/HP uses the BCM5701/5703 for this hardware (although I know that VMS supports only certain versions of this hw, sigh). No offense, and good luck! |
