Description Giuliano 2016-05-26 04:33:40 UTC
Dear Sir,

I have tried to install FreeBSD 10.3 at HP Proliant ML110 Gen9 and the NIC driver does not work. The NIC is a Broadcom 5717 C. The driver is not attached during boot and the ifconfig returns only loopback interface.

I have tried install Debian and tg3 driver Works. Also, DragonFlyBSD Works with if_bnx driver.

Best regards,
Giuliano Sperandio

if_bnx [1] seems to correspond with the if_bge [2] driver based on the driver description in the respective manpages.

Could you please attach your pciconf -lv output for the machine from DragonflyBSD?

Dear Ngie Cooper,

I have attached the output pciconf at file pciconf.out.txt.

DragonFlyBSD has also a if_bge driver. I cannot understand the difference between if_bge and if_bnx, they seem to be quite similar.

Comment 4 Giuliano 2016-05-26 13:15:04 UTC
Actually, I have tried first to install FreeNAS 9.10. As the system doesn't works, I started to look for why it is not working.

As I could retrieve, the source code of DragonFly BSD includes the 5717 C NIC at if_bnx. The FreeBSD if_bge source code includes only 5717 A and 5717 B NICs. The 'C' version is missing.

5717C patch
Comment 6 Sepherosa Ziehau 2016-05-26 14:26:43 UTC
Heh, it was added a long time ago.

And as for why bnx(4) in DragonflyBSD, its mainly because the bnx(4) support 4 RX rings on all chips, and 4 TX rings on 5717C/5719/5720, and well of course multi-vector MSI-X support.  Adding these stuffs to bge(4) caused too much trouble for me back to 2013, bge(4) is already too complex.

I have attached the patch for FreeBSD bge(4) to take over 5717C, please test.

Dear Sepherosa,

I wish to thank you very much for your help. I'm sorry my ignorance but I have looked for how to compile this patch and I did not found. Is it possible to return the necessary commands to do this? (or a link with instructions)

Best regards,

cd /usr/src
fetch -o - https://bz-attachments.freebsd.org/attachment.cgi?id=170681 | patch -p1
Comment 9 Giuliano 2016-05-26 20:52:52 UTC
Dear Ngie,

I have triple checked typing to be sure it is not my mistake. There is a error: fetch: No match. Hmm... I can't seem to find a patch in there anywhere.

Best regards,

The command I provided is for use with FreeBSD.

Add single-quotes around the URL or escape the question mark:

cd /usr/src
fetch -o - 'https://bz-attachments.freebsd.org/attachment.cgi?id=170681' | patch -p1

(In reply to Stephen Hurd from comment #11)
Dear Stephen,

single-quote makes fetch command works. But the patch command ask for 'File to patch:' and I have no idea what to type. Is it possible to have a new module to execute kldload?

Best regards,
Comment 13 Giuliano 2016-05-27 21:15:05 UTC
(In reply to Giuliano from comment #12)

What I did:
- I follow the steps showed in the link below (until the Step 3).

- Add the patch in the attachments
cd /usr/src
fetch -o - https://bz-attachments.freebsd.org/attachment.cgi?id=170681 | patch -p1

- Do the remaining steps 4 and 5.

I wish to thank Ngie Cooper, Sepherosa and Stephen -- otherwise I could not solve this problem.

Best regards,
Giuliano Sperandio
