Broadcom 57xx VLAN info striping

[red_on_line]

Hi everybody,
I've got an issue to solve on driver Broadcom 5751 on Debian 4.
The network device was correctly installed and the tg3 module is working fine. However when I try to capture the packets in a tagged environment, the VLAN id information and CoS are stripped away from the card and Ethereal doesn't show such information.
I know this issue because I had the same problem working in Windows environment. In such a system the Broadcom driver has a variable to be set in the register to preserve VLAN information (i.e. PreserveVlanInfoInRxPacket).
Do you known if there is a similar setting for Linux? Maybe a parameter must be passed to tg3 module or to ethtool command.

Thanks for any help.

Hi everybody,
the Broadcom support wrote to me a working solution for the problem. It works for me, I hope that this can be useful to someone else.

0. Download the b57udiag ISO file from Broadcom.com->download->driver
1. Create a bootable CD using the b57udiag ISO file
2. Boot to DOS using this CD
3. Choose option one on the FreeDOS 1.0 Final Cut CD menu
4. Choose option "Install to HD using FD setup
5. Run FreeDOS from CD ROM (return to command prompt)
6. cd to b57diag and run "b57udiag -cmd"
7. At the prompt enter "setipmi -d"
8. At the prompt enter "setasf -d"

Bye
