hi,
1. It is possible to change the configuration of the CX3 NIC to accept 10G over 4 lanes.
2. Can you please share the .ini of the OEM (using the aforementioned 'flint dc' command)? We will need to change the CX3 NIC .ini in accordance to the OEMs ini settings for CX4 communication (3.125gpbs over copper).
Thanks,
Dan
