[dts] How to disable the BOOTP and LLDP packets on tester ?

Thanks for your reminder.
I can bind this old firmware x710 NIC on my Tester.

BTW, I found the firmware boundaries are 4.33 and 4.40 in i40e_main.c. What's the main gap for x710 6.0 firmware and 4.41 firmware?

Thanks,
Phil Yang

X710 firmware=4.41 is too old to use, currently we all used X710 with firmware 6.01

I really appreciate your help, Marvin.

The firmware for XX710 is firmware=6.01 and for 82599ES is firmware=0x61b20001 and for X710 is firmware=4.41.
Just as you mentioned, debugfs can only work on x710 firmware=4.41.

Thanks,

Hi Phil,
Just both debugfs and hard-coded code will call the same function i40e_aq_stop_lldp at the end.
So I think if firmware version is 6.x, still can't disable LLDP by debugfs.
And In my mind, we do not have user manual for NIC configuration.  Most of time, we get the such information from code :)

Thanks,
Marvin

Hi Marvin,

Thanks for your guidance.

I got some tips from serverfault.com, so do you have some manual for Intel NIC runtime configuration?

Phil,
BOOTP is the packets sent by dhcp client. You can check whether Network-manager or dhcp client running in the background.
For LLDP packet, FVL with firmware6.0 can't disable it. If FVL with firmware 5.X or lower version, you can disable it in i40e driver.

i40e_main.c
//pf->hw_features |= I40E_HW_STOP_FW_LLDP;

Thanks,
Marvin

Hi Marvin,

I captured groups of bootp and LLDP packets while running DTS on DUT PMD.

My environment:
Application: l2fwd
DUT NIC: 82599ES
Tester NIC: X710
Link:
Tester           <------>       DUT
X710 port A <-------> 82599ES port A
X710 port B <-------> 82599ES port B

Please check the attachment. Thanks.

Ps: I didn't find lldpd service running on my tester.
