Bug 208653

Summary:	PCN driver will not handle all PC net pro cards
Product:	Base System	Reporter:	Mats <mats42>
Component:	kern	Assignee:	freebsd-net (Nobody) <net>
Status:	Closed Works As Intended
Severity:	Affects Some People	CC:	amd64, sbruno
Priority:	---
Version:	10.3-BETA2
Hardware:	amd64
OS:	Any

Description Mats 2016-04-09 12:24:10 UTC

Please update the PCN driver so that it will handle fibre adapters based on the PCnet-pro chipset (IE allied telesis 270X) series cards.

Currently the driver will detect the card but not initialize it properly.
(there is working code in the Linux driver that might be useful for backporting - im not skilled enough to determine that but I want to mention for inforamtion)

I'm not a C developer but I can ofcourse help with testing of this issue

The best thing I can suggest, is to post a "pciconf -lvbc" from the system and lets see if just adding pci-ids helps.

Since we see a pcn0 it seems (in my eyes at least, the may be wrong) that the driver detects the card. 
It just wont handle it right. If I understand the linux code, this nic must be set to 100FDX since a fibre adapter can't support anything else.
I did try ifconfig pcn0 media 100baseTX -mediaopt full-duplex
That gave an SIOCSIFMEDIA (media): Device not configured

(In reply to Mats from comment #3)
Hrm ... fiber eh?

what about using 100baseFX in the media type when you use ifconfig?

List the media types with an "ifconfig -m pcn0"

Maybe that will help us move forward.

Comment 5 Mats 2016-04-20 16:57:10 UTC

Brown paper bag in head-size ordered :)

I must have done something wrong yesterday then i tested ifconfig pcn0 media 100baseTX -mediaopt full-duplex because it worked today.

Big thanks to you Sean Bruno for the help. 
I'm very happy right now to get the card working. I do live far out on the countryside. My internet connection is DSL over arial wires so I do have some lightning problems. By Connecting my DSL modem to a fibre connector and then a Fibre cable to the now WORKING card I got a very effective protection. Sure, I may still loose the modem and the converter but I can buy that second hand for about $30. Thats a lot better than loosing a $2000 computer.

PS. Sorry for reporting a non bug. Ds

Groovy.  I'll close this out then.

Comment 7 Mats 2016-04-20 17:17:02 UTC

Yes Please.

The only improvement I can see is that it would be nice if the driver would set "media 100baseTX -mediaopt full-duplex" by default if it detects a fibre only card since a fibre card only can be full duplex and the don't support autospeed either.

But that's just a small improvement.
