ixgbe XAUI operation mode

[jackbar13]

Hello,

I have an 82599 and i want to enable XAUI operation mode.

In the datasheet it's said that it could be forced by software by manipulating AUTOC registers...

Is it possible to manipulate those registers throw a utility ? or should i modify the driver and add a functionnality for this ?

Thank you.

Hello @jackbar13,

Thank you for posting in Intel Ethernet Communities. 

1) Please advise if you are using custom board or with which brand/OEM system board?

2) Linux distribution: 6.5-rc3 kernel is working on which Debian Trixie? May I also inquire on which ixgbe drivers that you tested with?

3) Ethtool -i 

4) Ethtool -k or sudo ethtool -k <interface_name>

Thank you.

Best regards,

Hi @B_Y 

1) I'm using two Intel PC's (server board) on which both of them have Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection and i want to communicate with FPGA which supports only 8b/10b.

2) I'm using Ubuntu 22.04.2 LTS and ixgbe 5.19.0-46-generic SMP preempt mod_unload modversions (?).

Hello @jackbar13,

Thank you for your patience.

After thorough research, we're unable to find the tool to manipulate those registers on Datasheet, page# 110: "3.7.1.1 XAUI Operating Mode" 

https://www.intel.com/content/www/us/en/content-details/331520/intel-82599-10-gigabit-ethernet-controller-datasheet.html?wapkw=82599ES%20XAUI&DocID=331520

Normally, Ethernet support representative will suggest user to a dedicated forum for questions on tools and embedded networking connectivity.

Based on the comments at  Embedded , it may seem the next direction require registration on Premier account, steps as following: https://www.intel.com/content/www/us/en/support/articles/000058073/programs/resource-and-documentation-center.html

We hope this clarifies matters for you.
